Hello! I see you’re encountering the "Error.appsnotowned" issue with Epic Plane Evolution. Let's work together to get this fixed for you.

This error typically means the app isn’t recognizing that you own the game properly on your device. To address this, I suggest the following steps tailored for your Android WebKit device:

1. Check Your Purchase Status:
- If you downloaded the app for free, this might not be the cause. But if you bought DLC or a paid version, make sure you are logged into the correct Google account that owns the game.

2. Restart Your Device:
- Sometimes a quick reboot refreshes the system and the app ownership info.

3. Clear Cache and Data of the Epic Plane Evolution App:
- Go to Settings > Apps > Epic Plane Evolution > Storage.
- Tap on Clear Cache first, then Clear Data.
- Note: Clearing data might reset your settings, but it can fix ownership recognition.

4. Reinstall the App:
- Uninstall Epic Plane Evolution completely.
- Restart your device.
- Reinstall the game from the official Google Play Store page to ensure a clean install and proper license verification.

5. Verify Internet Connection:
- Make sure you have a stable internet connection because ownership verification often requires an online check.

If after these steps the issue persists, it might be a bug on the app side or a server verification glitch. In that case, contacting the app’s support through their official channels or at [email protected] may help.

Please try these and let me know if the problem continues or if you need help with any step! Are you satisfied with this solution so far?
