This problem comes from the fact that the Android TV device, once in deep sleep, no longer listens to the commands sent by the application.
The only solution is therefore to deactivate deep sleep. This will lead to higher power consumption for your device.
- Press the “Home” key to access the Android TV home screen
- Click on the cogwheel at the top right of the screen: “Settings“
- Go to “Device Preferences / Advanced Settings / Energy Saving / Deep Sleep“
- Disable deep sleep
