Quell games progress is not being restored on Android Q

Hello

I just bought a new device with Android Q and although Google Play Games has synced my accounts and the games login into my account they do not restore my progress from my previous device. 

I can see my achievements in Google Play Games, but nothing is loaded by any of the Quell games (Quell+, Quell Reflect+, Quell Memento and Quell Zen). 

This is not happening to other games like Injustice Mobile 2, Kingdom Rush Origins or Empire Warriors. These games are restoring the progress correctly. 

Are you aware of this bug?
