Hello! I understand you're having trouble with submission in the Merlin Bird ID app, even though your internet connection seems fine. Let's work together to address this issue.

To start, could you let me know a little more about the situation? For instance, are you receiving any error messages when trying to submit? Also, have you tried any troubleshooting steps so far, like closing the app and reopening it, or checking for updates?

In the meantime, here's a general step-by-step approach we can take:

1. Update the App: Make sure that your Merlin Bird ID app is updated to the latest version available on the Google Play Store. Sometimes, updates include fixes for bugs that could be causing issues.

2. Restart Your Device: A simple restart can sometimes clear up any background issues affecting app performance, so feel free to restart your Android device.

3. Check App Permissions: Ensure that the app has the necessary permissions to operate properly. Go to your device's settings, find 'Apps,' select Merlin Bird ID, and check if all permissions are granted, especially those related to mobile data.

4. Clear Cache: You can try clearing the app's cache, which might help resolve any data glitches. Go to Settings > Apps > Merlin Bird ID > Storage > Clear Cache.

5. Reinstall the App: If the issue still persists, you may want to consider uninstalling and reinstalling the app. This can refresh the app’s installation and settings.

If none of these steps resolve the issue, it may be helpful to check if there are any known outages or issues with the Merlin Bird ID services. I can look that up for you if needed.
