Hi there! I understand you're having trouble with the interior accessories not working in Truckers of Europe 3 on your Android device. Let's dive in and get this sorted out.

First, I’d like to ask a few quick questions to better understand the situation:
- Are you unable to see the interior accessories option at all in the game menus, or do you see the options but they don’t apply correctly?
- Did this issue start happening after a recent update or installation of DLC (downloadable content)?
- Have you tried restarting the app or your device?
- Is your game fully updated to the latest version available on the Play Store?

For common issues with interior accessories in Truckers of Europe 3, here’s a step-by-step approach to troubleshoot:

1. Verify Game Version and Updates
Make sure your Truckers of Europe 3 app is updated to the latest version. Sometimes interior accessories require the most recent update to function properly.

2. Check for DLC or Interior Accessories Packs
Are the interior accessories part of an update or DLC you have installed? If this content is separate, ensure it is downloaded and installed correctly.

3. Clear App Cache
Since you’re on Android 10, clearing the app cache can resolve glitches:
- Go to Settings > Apps > Truckers of Europe 3.
- Tap Storage.
- Hit Clear Cache (not Clear Data to avoid losing your profiles).
Then reopen the app and check if interior accessories work.

4. In-Game Settings
Double-check in the game’s settings or customization menus that the interior accessories toggle or options are enabled or unlocked. Sometimes, you might need to unlock these by gameplay progression or credits.

5. Reinstall the Game
If none of the above works, uninstall and reinstall the game. This ensures a fresh installation without corrupted files.

If after trying these steps the interior accessories still aren’t functioning, it could be a bug or a known issue with specific truck models or updates. In that case, I can provide some community-sourced fixes, or you might want to keep an eye on official updates or community forums where similar issues are discussed.

Would you like me to guide you through any of these steps in more detail? Also, please share if you attempted any of them already so I can tailor my advice better.

Looking forward to helping you get those interiors looking great!
