My stick overheats while I was watching Apple TV. Waited 10 minutes and after about 10 minutes it's got the same message of overheating.
Thanks for the post.
We would recommend taking a look at the troubleshooting steps provided by our Support page here: Fix an overheating issue
If you are still unable to resolve the issue, can you please provide the serial number of your Roku device from Settings>System>About? I'll be able to assist you further from there.
Thanks,
Danny
