been a anti google LineageOS fan for years..might try Graphine on my next android ..i can zap with blue wallet Mobile ...first time when i tried to zap it asked which app to use...since then its fine..as far as getting zapped i set up getalby via my desktop browser and added the LN address to my profile .it all works 😁 i cant zap you as it seems you dont have a wallet connected at the moment?? let me know when you do and ill zap you a few sats
