Teams Mobile App - Audio connection lost after change between mobile network and wifi

Hi DominikA9522 ,

If you are experiencing audio connection issues in the Microsoft Teams mobile app when switching between mobile networks and Wi-Fi, there are a few troubleshooting steps you can try to resolve the problem:

1. Check your network connection: Make sure you have a stable and reliable network connection, either through Wi-Fi or mobile data. Poor network connectivity can cause audio disruptions. Try switching between Wi-Fi and mobile data to see if the issue persists on both connections.

2. Restart the Teams app: Close the Teams app completely and reopen it. This simple step can help resolve minor glitches and refresh the app's connection.

3. Clear app cache (Android): If you are using an Android device, clearing the app cache can sometimes resolve issues. Go to your device's Settings, find the Apps or Applications section, locate Microsoft Teams, and choose the option to clear the cache. Please note that this may log you out of the app, so make sure you know your login credentials.

4. Reinstall the Teams app: If the problem persists, try uninstalling and reinstalling the Microsoft Teams app on your mobile device. This can help fix any potential software issues or corrupted files.

5. Update the app: Ensure that you have the latest version of the Teams app installed on your device. Developers often release updates to address bugs and improve app performance.

Remember, these troubleshooting steps are general recommendations, and the exact steps or options available may vary depending on your specific device and operating system version.
