i have been pretty persistent with problems and choosing clients that seem to function best - coracle and primal are my go-tos and i don't use mobile at all, and anyhow, because i'm building nostr stuff i use it even sometimes just to talk about my work and test my relay
but i think overall the standard of reliability of clients and relays is still in the early beta phase... still so many wonky, quirky things, insecure, buggy clients and relays...
i personally tried to use amethyst on my motorola G51 running android 12 and my last attempt it was rejecting my valid nsec - so then i installed plebstr and then after that again decided that using it on mobile was not a good idea
and i quit using social media altogether 3 months ago, it was almost a whole month before i came back to nostr after about a month on it last year
you will not regret to stop posting, or even just reading that trash on Xitter and the rest, once you get used to it
i follow some news sites that are generally decent but that's it for my contact with the media... it's just not good for your mental health
