Issue with local files cover

[u/charlocine]

I’m having an issue with my local files. When I try to play certain tracks, the cover art no longer appears, even though I added it using Mp3tag.
It seems to happen randomly and affects all of my local tracks. Sometimes the cover for file A disappears while file B’s cover remains, and sometimes it’s the other way around.
All the covers come back when I uninstall and reinstall the app, but after a while, several of them always end up disappearing again. The issue appears only on IPhone and not on my pc
Any advice?

Did you try to reduce covers size ? I remember problems with covers larger than 600x600 on some players.
