A. 1. Restart your smartphone and the hearing aids. This can often resolve temporary connectivity issues. 2. Ensure that the app has the necessary permissions to access Bluetooth and location services, as these are often required for proper functioning. Go to your phone's settings, find the app, and check permissions.

B. 3. Uninstall and reinstall the Oticon Companion app. This can help clear any corrupted data that may be causing connection issues. 4. Make sure that your hearing aids are compatible with the app version you are using. Check the manufacturer's website for compatibility information.
