Says to “Update App” won’t let me – Shop, Play, Win!® MONOPOLY Review

I don’t know what I’m supposed to do because you can’t contact customer service and it won’t allow me into app anymore, it just says “update app” and brings me here and even redownloading didn't help. So now I have tokens I can’t even redeem. I’m annoyed.
