I won't discount hardware issues but my experience is consistent across 6 different phones now so make of that what you will.
All of this aside I still wholeheartedly recommend bandcamp, I still think it is best for both variety of things available (particularly for niche genres) as well as artists actually getting paid.
The app still works absolutely fine I just would never describe it as "great" personally, it is just annoying because a lot of the issues I have could be resolved fairly easily and have been present for many many years at this point.
