It seems like Beograd Plus app reappeared for smartphones which doesn't pass Play Integrity check (in my case it's GrapheneOS), didn't test it yet, but probably should work now... Otherwise I don't know why would they made it available again.
Does it require BASIC or HARDWARE_BACKED check? I use Pixel with GrapheneOS and recent version doesn't work (installs but didn't allow to purchase a ticket).
Also what does it use in case of Huawei's AppGallery? They have an alternative for Play Integrity API?
Sorry for English, I currently don't speak Serbian. But I could answer. I use GrapheneOS for almost 2 years now, installed on Pixel 6a. It's excellent OS with a lot of security improvements and privacy features. I like it and don't think will switch to stock Android or iOS in near feature...
