I put primal on my iPad, but struggling with set up. Transferred my pub key from Damus. Went in and picked everything up, but won’t let me comment, add, Zap or anything at all. Went into profile and added my lightning wallet address, but it won’t stick. I hit save, exit the setup and come back and it’s not there any longer.
It’s only right that nostr:npub16c0nh3dnadzqpm76uctf5hqhe2lny344zsmpm6feee9p5rdxaa9q586nvr came through with the first zap on the shiny new #Primal Lightning address! Also had to zap myself ofc. 😁

It sounds like you need to sign in with your private key. If you use your public key, the app will be read-only. Let me know how it goes or if you have more questions.
