Can add that, for mutes it's already there, but not yet for unfollows 😅
What sign in method are you using? Nostr-login?
Discussion
I used the nos2x extension to login and sign events within the Kiwi browser on my android phone. Could be also because my mobile connection is to slow and the unfollow process requires more time before hitting the button again.
I had this kind of loading issue while speed zapping back in the early Nostr days of #zapathon
I never was able to zap as fast as nostr:npub1ezw0xm0w52rd4yfdg9zlw9qvwdy46alzelklkefptrd203m37tuq4djmeg 🤣
Unfollow all button should be available now
