I reproduced the 3 issues while debug mode was active (tweaking theme settings, rating songs and activating/deactivating country in about album page settings)
Reproduction steps:
The first ss shows the country tag is already tagged
The second one shows the theme issue and country issue
The third one shows my custome theme in 11.4 stable release
The last one shows the same custom theme in the latest beta
Please don’t mix completely unrelated issues in the same issue it’s impossible to follow.
For the country part, that tag does not exist see for example Tag Field Mappings – Mp3tag Documentation for valid tags for that.
With that said I can probably add support for that custom one.
Haptic definitively works unless disabled at os level.
Edit: For the theme part, Google fixed the chips outline to be consistent per the spec. So the border is now outlineVariant and no more outline. (This is consistent with your buttons at the top that does not have a border in your theme.)
