I recently upgraded my TCL Roku TV to the latest update that allowed it to support Airplay and HomeKit. After I set everything up, it worked great for about an hour and then went to “no response” and will stay that way for hours. Sometimes I might get it working properly, but most of the time it’s definitely “unanswered”. I will separate it from the HomeKit and reset it, and it will run again, but it will take about an hour for it to return to “no response”. Interestingly, Airplay works well even when HomeKit is not.
Maybe this is just a growing pain, because HomeKit on Roku is pretty new, but I thought I’d throw this in there if there’s an obvious solution I don’t know about.
