Shib isnt working on my binance mobile app

As title says I have problems with shib on the binance mobile app main problem being that I've always had it starred as one of my favourite to watch closely and recently for some reason it never shows up on my favourite tab but it's there on the normal crypto listing and when I star it again it says added to favourites but then all the numbers go to a 0 and if I check my favourites tab it's still not there and them when i go back to the normal listing it's still there and says I never favorited it. It also seems I can't trade or sell it (not that I want to atm) and that worries me for the future seeing as it's my most invested crypto atm . Any tips or help is much appreciated
