Kept on showing error even after purchase

Application kept on showing me “You need to login to see your submission”.
I logged out from account from all other devices, also did log out and login back to app. It randomly shows submission sometime only 1st time after login and start showing same error message again.

I upgrade the version to pro. This is very frustrating to not able to explore the feature even after making purchase.
