2. Force Stop the App:
- In the same menu, look for the option to Force Stop the app. This helps to reset it.

3. Check for Updates:
- Still in Settings, navigate to My Fire TV and then select About.
- Choose Check for Updates to ensure your device has the latest software.

4. Restart Your Fire TV Stick:
- You can either restart it from the Settings, or simply unplug it from the power source for a minute and then plug it back in.
