Been running 0.1.4 for several weeks now, but I have never been able to send any messages. I can see my list of Nostr contacts, but when I select a contact and tap “Start Chat”, I receive the error messages “Something went wrong. Please try again.” or “Failed to share invite”. I would like to resolve this issue. Is there a community forum where I can get help?
