Photoshop on iPad Pro says check connection and won’t sign in to main profile

I have premium Photoshop on the latest iPad Pro on the latest version of IOS and any time I try to log in it hangs on a screen which states to check the network connection, which it is fine, then just constantly hangs on the same screen. Whenever I press restore purchase it tells me everything is up to date. Have tried deleting and reinstalling and signing into different accounts which works but my main account doesn't. Any suggestions?
