I bought the game but it says I need a license

My device is Xiaomi Mi Max 3 128 GB.

 

I bought Minecraft on the Google Play 1 year ago, but after after I updated to 1.8.0.13 beta, it says I need to have a license to play the game.

This didn't happen when I played the game in previous versions, and when I played this yesterday running the same game version this didn't occur.

P.S. I know the photo is in Chinese but the idea is there.
