It is messed up!

I would rate Pou a 5 star because I enjoy playing but recently it has been messing up and it wont let me login g into my account. It says I need to update the app and its been four days now but it still shows there is no update. My pou is level 53 so I dont want to give up on it just yet because Ive put a lot of t me into this app. Any helpful ideas?
