3 years ago quran.com is correct as per the King Fahd Quran printing complex. the text is written without tajweed, but when you recite it, you recite it with tajweed and therefore say it as mayyaqoolu - but the written is man yaqoolu.
orignal is وَمِنَ النَّاسِ مَنۡ يَّقُوۡلُ اٰمَنَّا
on quran.com وَمِنَ ٱلنَّاسِ مَن يَقُولُ ءَامَنَّا the ayat should be min-nan-naasi mayyakulu but on quran.com it's written as min-nan-naasi manyakulu
