What client are you using? There is a growing number of them, but please keep in mind that all of them have just started out because the Nostr protocol itself is very new. Unlike centralised networks that have been around for decades, there just hasn't been enough time to reach that kind of maturity, where everything works flawlessly. Please be patient. Try other clients as well. 

 Everyone keeps telling me that.
But how mature does something need to be, to do something simple like follow or unfollow?

It’s been an hour and ive barely been able to remove 40 follows. And half the time when I follow a new account, it doesn’t show up in the list. Have had to quit & restart the app 15 times now. (Primal btw)

This shit seems basic.
