Hi Max! Thank you for the new update, however, with the introduction of the Parametric Equalizer my graphic equalizer presets were gone. Glad I had a backup of my PA settings. Wanted to make a bug report because I experienced it twice on 2 different devices, a Samsung (Android 11) and a Realme (Andeoid 10) phone.
@invaderzim have you switched to parametric mode? It has no graphic presets, but it still have some built in ones. Presets are not deleted, there is no code for that, but some visibility issue probably can happen, though, not reproducible.
Could you please send your backup or folders.db to firstname.lastname@example.org? Thanks!
