How come I cannot seem to un-fan anyone anymore when on a ファンポップ mobile site?

Does anybody else have the same problem like me? Any other mobile user out there? I have an Android phone btw. For some time now I've been having problems with removing unwanted people from my fanlist, yet this is simply ridiculous! Everytime I try to remove a so called fan, nothing happens! All I can see is a note: 'Oops!! Something went wrong. Please try again!' No matter how many times I try, there's just no effect, または should I say there's absolutely no result whatsoever. It doesn't make any sense to me! I don't get it! If we can add people to our fanlist when on mobile site, we should also be able to remove people from our fanlist the same way. Is it because I'm (still) using a classic Fanpop, instead of a modern one? Thank あなた for your answer & for your help, also on your アドバイス on how to fix this problem, dear mobile users.
