TRAIN button is greyed out in Kick Off tutorial

Hello, I am stuck in the Kick Off tutorial. The TRAIN button is greyed out and I cannot start the tutorial or continue the game.

Device: Redmi Pad Android 12 MIUI Pad Global 13.1.7 Game Version: 27.0.03

The game is installed from Google Play. I updated it, restarted the device, cleared cache, and tried different networks, but the problem is still there.
