That such stories emanate from the Catholic Church would lead any intelligent person to form an opinion about the Catholic Church, one way or another way.
It is true that, as far as I can find, no valid, Protestant spokesperson has claimed to be able to be in two places (on earth) at the same time.
Nor did any Old Testament prophet. Nor did any Apostle.
Nor was the Lord Jesus, in his humanity, ever recorded to be, though he did say, whilst his own human feet were on the earth :
... the Son, of man, which is in heaven ... John 3:13 KJV (plus two commas in context).
To be 'made sit in heavenly (places)' Ephesians 2:6 (KJV and Douay Rheims) is a privilege shared by all persons still on earth, who are true believers in Christ. I am uncertain whether this is classed as 'bilocational'.
If that is accepted as 'bilocational' then I suppose that all true Christians have such a privilege.
Συνεκαθισεν 'made sit together' is in the past tense - strictly speaking, the aorist tense - and so is true now, and is not a matter of the future bodily resurrection. [See Bagster's Analytical Lexicon 'συνεκαθισεν .. third person, singular, aorist 1, indicative'].
And this agrees with the words of the Lord Jesus that, whilst on earth, he was simultaneously in heaven.
For the kingdom of heaven is come among us and those who repent and believe, enter therein, as saith a multitude of scriptures. See 57 verses about Entry into the Kingdom of Heaven.
Even when we were dead in sins, [the Father of glory (1:17)] hath quickened us together with Christ, (by grace ye are saved;) and hath raised us up together, and made us sit together in heavenly places in Christ Jesus. Ephesians 2:6,7 KJV.
