Unable to use MoveBase - Forces me to update despite latest version

When I opened today MovieBase (on Android, Huawei P30) there was a popup that I must update it to use it. I went to the Play Store, updated it, but it still shows that popup, therefore I can’t use it (despite today buying the premium plan!). Uninstalled and reinstalled it, didnt help. Please fix this asap!

Thank you
