Quick fixes
- Update the app. Open the App Store or your Android app store and install any Deku update. Many problems are fixed in newer versions.
- Update your phone. Install any pending system updates.
- Restart. Close the app fully, then restart your phone.
- Check your connection. Tournaments need a steady internet connection. Try switching between Wi-Fi and mobile data.
- Free up space. Low storage can stop an app from loading.
Crashed during a tournament?
Reopen the app as soon as you can. If you come back while your play window is still open, you continue from your last saved point. See What happens if I leave a game or the app closes?
