Shifting meaning of sola scriptura
As with most key concepts that survive for centuries (along with the terms that label them), it is very important to keep in mind that a label's meaning shifts over time, driven by how communities that use them intend to use it for teaching, slogan, or identity. Example from politics: according to The Atlantic 2014 article The Origin of 'Liberalism', when Adam Smith used the word "liberal" in the political sense in his 1776 classic book The Wealth of Nations, it meant a political system which is free of government intervention, which in the United States is represented today by the "conservatives" such as the Republican Party while the word "liberal" in United States now means social liberalism represented by the Democratic Party.
Similarly, the slogan Sola Scriptura which the 16th century Martin Luther did mention ("solam scripturam regnare"), meant something else to the 13th century Thomas Aquinas ("quia sola canonica scriptura est regula fidei", Commentary on John 21) and probably meant something else to 3rd century Hippolytus ("There is, brethren, one God, the knowledge of whom we gain from the Holy Scriptures, and from no other source., Against Heresies 9).
However, many scholars (such as Keith Mathison in his book and paper) feel that in the late 20th century the concept of Sola Scriptura (as it's being used among Christians today) has degenerated into becoming "solo scriptura", divorced 100% from other legitimate authorities (like the early creeds and ecumenical councils), whose meaning is significantly different than what Luther has meant by sola scriptura in the 16th century. This recent development prompted the invention of the term Prima Scriptura in 1997 although the concept may have started with 18th century Wesley's Methodist Quadrilateral methodology to prioritize the 4 sources for theology: "chiefly scripture, along with tradition, reason, and Christian experience."
At least 4th century Augustine Actually (and Clearly) Affirmed Sola Scriptura in the 16th century Protestant sense based on research done by Gavin Ortlund in his recent two books published in 2019 and 2020) who explains in a 25 minute video, providing three Augustine quotes and one John Chrysostom quote that he guaranteed were not taken out of context after he first clarified many misunderstanding of sola scriptura by Catholics and Protestants alike.
But both prima and sola still mean that scripture has authority above tradition
The question for us today is which sola scriptura are we talking about? If we compare the 16th century meaning of sola scriptura and todays meaning of prima scriptura (which currently seems to be the same as 18th century Wesleyan Quadrilateral) the most important common factor is the Reformation principle that
Scripture is the only infallible rule for faith and practice.
Tradition has a place. Creeds and councils can be binding and authoritative. But all that is subsequent to Scripture is reformable in light of Scripture.
sola scriptura also does NOT mean the Bible is the only authority or the exclusive source of all theological knowledge (source: Justin Taylor's article mentioned above).
Furthermore, Justin Taylor explained "The Real Meaning of Sola Scriptura" in his 2020 article One Rule to Rule Them All, quoting from Robert Letham's 2019 Systematic Theology:
[There is a] false notion, held widely, that the slogan sola Scriptura means that the Bible is the only source for theology. . . .
The slogan itself, still less the reality to which it pointed, never meant that the Bible was the only source for theology. The dangers of such a position are most clearly seen in the Socinians, the Jehovah’s Witnesses, and in the early Plymouth Brethren, who, in their first decade, recapitulated many of the heresies of the early church.
When the slogan [sola Scriptura, Scripture alone] was devised, it was never intended to exclude the tradition of the church.
and from analytic theologian Oliver Crisp 2009 God Incarnate: Explorations in Christology:
[First-Order Authority: Scripture: The Rule that Rules]
- Scripture is the norma normans ...
[Second-Order Authority: Ecumenical Creeds: Rules that Are Ruled]
- Catholic creeds, as defined by an ecumenical council of the Church, constitute a first tier of norma normata ...
[Third-Order Authority: Confessional Statements: Rules that Are Ruled]
- Confessional and conciliar statements of particular ecclesiastical bodies are a second tier of norma normata ...
[Doctrines from Theologians: Legitimate Theological Opinions]
- The particular doctrines espoused by theologians ...
... and thus share the same biblical basis

A response to Ken Graham's answer: What Ken is offering is not how the term Prima Scriptura is used among Protestants, which the OP implied since he quoted from the wikipedia article Prima Scriptura. The wikipedia even says that for Roman Catholics there is "total equality of Scripture with Sacred Tradition", which Protestants still deny to this day. @curiousdannii's comment is worth preserving:
If Prima Scriptura is used by Catholics, then this would indicate a difference in meaning: where Catholics see it as the prime source, Protestants see it as the prime authority. It's not incompatible for scriptura to be the prime source of Christian knowledge while the Magisterium is the authoritative interpreter of scripture. Whereas Protestants would reject that strongly
A response to SpiritRealmInvestigator's comment about cessationist vs. continuationism implying that sola scriptura is cessationist while prima scriptura is allowing continuationism. The two debates are addressing different issues. Sola scriptura is set against the Catholic Church's claim that Tradition is on the same level with scriptures (as a source) and that the Magisterium is the authoritative interpreter of scripture. Continuationist allows valid prophesies today, but they also say (whether sola or prima doesn't matter) that scripture has higher authority than prophecies.
