Android app requires update, but no update is available on Google Play

Hello! I can't open Moviebase on Android. When I open the app, I get a message saying that I need to update to the latest version in order to continue using it. However, when I go to Google Play, there is no update available and the app is already shown as up to date.

I'm currently unable to access the app because the update screen cannot be skipped. Could you please check this issue? Thank you!
