I'm not missing any features that I'm aware of. The app is just really slow and laggy and keeps crashing. I can't really do much on it without it crashing

Interesting, it hasn't crashed for me yet. My guess would be memory consumption - try killing other apps you have running and reduce number of relays to like 6 or so...

Really. What kind of phone you on? I'm on amethyst and I'm super happy. Runs well. OK its true it can be a bit slow to load sometimes but relays make a big difference there. Are you on any paid relays? Nostr.wine is a good one. #[5] #[6] are the dude and dudette behind it. I'll shout you a sub...
