The desync starts at 2:9 https://quran.com/2?startingVerse=9 but only if you manually play it. If you start playing from 2:8 or earlier verses and continue up to 2:10, it'll work. However, if you refresh and play 2:9, it'll be out of sync again.

I also want to note that these issues occur when AbdulBaset AbdulSamad is selected NOT AbdulBaset AbdulSamad -Mujawwad which works fine.
