Thank you so much for this very detailed response. Started with Iris on Android, but found that Amethyst was a little more to my liking. Primal sounds like it is worth a test drive. Especially because of the better statistics. I have noticed delayed and strange follower counts, missing zap stats that don't add up sometimes in Amethyst and Iris. Another kind Nostr also recommended Alby when I joined recently, and you're right it has been a great extension.
I appreciate you taking the time to respond and hope you have a wonderful weekend! <3
