Amethyst has always been my daily driver but the last couple updates it's been so buggy for me that I've been forced onto ditto. I still open amethyst if I want to post a picture because it automatically uploads to my nostr.build account and Ditto doesn't.
The four clients I have on my phone are Amethyst, Ditto, Yakihonne, and Primal. Primal is the one I never use except for verifying issues with other clients. Like if NWC breaks in Amethyst and still works in Primal then I know the issue is with Amethyst and not Alby.
Could be. If I delete the app connection in AlbyHub AND delete the Amethyst app data in my phone, and then reconnect NWC it will work for a couple days before it breaks again. Works fine anytime I try it with Primal. I think it's a stale cache issue.
It's likely a tor circuit building issue. Try clearing all data (not just cache) and signing back in, I'll bet you it starts working again. Fix hopefully in the next update.
That's what I have to do. Yeah. Clear all data and sign back in. It's not worth the trouble of having to do every couple of days. I just hand zaps off to the AlbyGo wallet app and accept that I can't have working NWC in Amethyst right now.
