I had problems with my Damus account as well. Mostly use Primal now. Much better 👍🏻

I keep both and use both regularly. nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg for zapa. nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 for scrolling, emoji reactions, etc. Damus seems to crash more often, bur I am on Test Flight and testing beta versions.
Damus latest version is on AppStore, not testflight. There might be a fix to bugfixes you are experiencing
