Hello amosfromvereeniging,
To help rule out software issues causing the behavior, check for an update to tvOS.
See how to check for an update to tvOS here: Update your Apple TV
Update your Apple TV manually
1. Go to Settings > System > Software Updates and select Update Software.
2. If there's an update, select Download and Install.
3. Wait for your Apple TV to download the update. Keep your Apple TV connected and plugged in to power until the update is complete.
After the update downloads, your Apple TV will restart, prepare the update, then install it. When the update is complete, your Apple TV will automatically restart again.
If it's running the most current software, then reach out to Apple Support directly to help investigate the behavior. They'll be best equipped to find the best resolution should the behavior persist. You can use the following link to reach out: Get Support
Kind regards.
