Hi there! I see your mail.com app keeps stopping even after you tried force stopping it and clearing cache and data. That can be tricky. To help you better, could you tell me if you’ve already tried restarting your Android device? Also, is your mail.com app and your device’s software updated to the latest versions?

Meanwhile, here is a step-by-step approach we can try beyond what you've done:

1. Restart your device: Sometimes a simple reboot clears out background issues.

2. Check for app updates: Head to the Play Store, search for mail.com app, and see if there’s an update. Running the latest version helps avoid bugs.

3. Check Android System WebView: On some Android devices, apps can crash if the Android System WebView component is causing trouble. You can search for “Android System WebView” in the Play Store and if there's an option, try rolling back to an earlier version or updating it.

4. Verify storage space: Ensure your device has enough free storage. Low space can cause app instability.

5. Check your internet connection: Confirm you have a stable network connection; switching between Wi-Fi and mobile data can help isolate the issue.

6. Uninstall and reinstall the mail.com app: Since clearing cache and data didn’t help, a fresh install can fix corrupted files.

If after doing all these steps the app still stops, it may be worth checking if the problem is related to your account or server-side. Let me know if you want to go that route or if you need guidance on any of these steps!

Are you comfortable proceeding with this?
