Hi, i have this problem on iOS and also Desktop, but since i use iOS more i have posted it here.

I have a large list of followed artists, but not all artists I follow remain as followed artists. A large number of artists i have followed no longer show in my Library->Artist list, and when i search for them in the search results they show as 'Followed Artist' but clicking on the search result to go to the artist page shows them as not followed.  If i click to follow them again they will temporarily show as followed and appear in Library->Artists, but after following a few more artists the original artist will have become unfollowed yet again. Some bands i have followed 40, 50 times in this way, and yet remain unfollowed. It's a massively frustrating issue and is sorely tempting me to move to an alternate service as I can't rely on following an artist to then check out later.
