If you're having notification issues, you can follow these steps to troubleshoot:
1. Check that 'Do Not Disturb / Focus' is not enabled: Forgetting to turn off Do Not Disturb/Focus is a common reason for not receiving notifications. If this setting is enabled, turn it off to start receiving notifications again.
2. Restart your phone: Many notification issues on your devices can often be fixed by simply restarting your phone. Whether it's a frozen app, a poor network connection, or any other issue, restarting your phone can automatically resolve these issues and save you from lengthy troubleshooting.
3. Ensure you haven't turned off system notifications: Always check the system notification settings first before searching for issues elsewhere.
4. Make sure you haven't turned off app notifications: If you're not getting notifications from a particular app, the main reason could be the notification settings for that app. Each app has its own permissions to access features, and notifications are one of them. Ensure that notifications are enabled for the ExpiWell app.
- Android-specific app notifications: Besides ensuring 'Allow notifications' for the ExpiWell app is enabled, please also ensure the following:

- Enable Alerts: Allow notification sounds and haptic feedback when receiving a notification.
- Enable “Lock screen” and “Banner/ Pop-up": Lock screen—so you can see it even when your phone is locked. Banner—so it pops up while you're using the phone.
- Enable "Allow in Do Not Disturb/ Override Do Not Disturb": Turn this ON so the app can still send notifications even when Do Not Disturb mode is active.
- Many Android apps categorize notifications into 'channels' (like 'uploadChannel'). Ensure these specific channels are also configured correctly. Under the app notification categories 'uploadChannel', please ensure the notifications and alerts are enabled and set to default mode instead of silent, as shown in the screenshots below.

5. Ensure you are logged in to the appropriate ExpiWell account: For reliable and timely notifications, ensure you're logged into the ExpiWell account you used to join the study. This is crucial because all push notifications for that study are sent to that specific account.
6. Ensure you have a steady network connection: A stable network connection (mobile data or Wi-Fi) is required for these notifications to reach you promptly. Ensure Data Saver modes are not enabled and your app's Background Data and Unrestricted Mobile Data Usage are enabled, as these settings can also ensure timely push notifications when the Wi-Fi connection is weak or spotty.
7. Check that your app isn't restricted from running in the background: Many apps that send notifications need to run in the background to work correctly. If Background App Refresh is turned off for an app, you might experience delayed notifications or not receive them at all. This is because the app won't be able to get new information when it's not actively in use. If you're using an Android device, ensure you have also disabled the Unused app settings under App info.
