Hi there! I understand that on your Android 11 device, Blue Mail shows emails in the list but when you try to open them, sometimes it works and sometimes you just see a flashing line next to the list. Let's try to get this sorted out together.

First, can you tell me if this happens with all emails or just specific ones? Also, have you tried any steps so far like restarting the app or your device?

In the meantime, here are some steps you can try to fix this intermittent email opening problem:

1. Force Stop and Restart Blue Mail App
- Go to your phone Settings > Apps > Blue Mail.
- Tap Force Stop.
- Then reopen Blue Mail and try opening your emails again.

2. Clear Blue Mail Cache
- Go to Settings > Apps > Blue Mail > Storage.
- Tap Clear Cache (do NOT clear data yet, as that could remove account info).
- Open Blue Mail again and check if the issue improves.

3. Check for Blue Mail Updates
- Open the Google Play Store.
- Search for Blue Mail and see if an update is available.
- Updating sometimes resolves bugs especially on Android 11.

4. Check WebView Component
- Sometimes email content rendering depends on Android’s WebView.
- Go to Google Play Store, search for Android System WebView, and update it if an update is available.

5. Re-add Your Email Account
- If the issue persists, try removing your email account from Blue Mail and adding it again:
- In Blue Mail, go to Settings > Accounts > Select your account > Remove.
- Then add the account again using the + (plus) button.

6. Check Network and Sync Settings
- Ensure your device has a stable network connection.
- Also, check if Blue Mail has background data and sync permissions allowed through:
- Settings > Apps > Blue Mail > Data Usage — Ensure background data is enabled.
- Settings > Accounts > [Your Email Account] > Account sync — Make sure sync is enabled.

If after these steps the problem continues, it might be related to a known app bug, especially since you mention "random success." In that case, checking for a newer app update or contacting Blue Mail support directly might be best.

Let me know how these steps go or if you’ve already tried any of them! We can dig deeper if needed.

Are you satisfied with this plan so far?
