As the title reads. I synced from my computer to my phone, which already contained all of my playlists, but this time I had checked "Use Extended M3U". After syncing, I tapped Playlists on my phone, and in real time I saw each of my playlists get replaced one by one with "0 tracks".
The computer:
Samsung Galaxy Book Go, ARM64 processor, Windows 10, running MMW 5.0.2.2524.
The phone:
Samsung Galaxy A12, running MMA version 1.4.5.0960
MMA doesn't read Extended M3U playlists
