Hi! I understand you’re seeing a “no internet connection” message in the Mystery Town app despite having connection and permissions enabled. Also, you want to check if there’s a scheduled maintenance causing this.

From what I’ve gathered, there isn’t an official public maintenance schedule readily available for Mystery Town at this moment. Often, when apps show connection errors, it could be due to server maintenance or temporary outages, but these are usually announced on official channels like the app’s social media or support pages.

To assist you better, could you tell me:
- When did the issue start?
- Is the app updated to the latest version on your Android 15 device?
- Have you checked Mystery Town’s official social media or support for announcements?

In the meantime, here are a few steps to help confirm if it’s a maintenance or local issue:

1. Check Internet on Other Apps: Verify other online apps or browsers work to confirm your internet is stable.
2. Restart the App and Device: Fully close Mystery Town and then restart your phone.
3. Update the App: Go to Google Play Store and make sure Mystery Town is updated to the latest version.
4. Clear Cache: In Settings > Apps > Mystery Town > Storage, tap “Clear cache” to reset temporary data.
5. Check Official Channels: Look on Mystery Town’s official Facebook groups or community pages where maintenance or outages are often reported.

If the problem persists after these steps and no announcement of maintenance is found, it might be worth waiting a bit or contacting Mystery Town’s support directly for up-to-date details. Let me know how it goes or if you want help with any of the steps!
