I thought I posted this issue, but I'm not seeing it and messed up. I see other topics about Prem TV and stopping, stuttering, etc. but none related to Apple TV and Live TV.
Any way, every so often while watching Live TV on my Apple 4K devices (3 of them), the screen will freeze, slight pixelation, then resume. Some times the audio has to catch up and some times the video will fast forward to catch up. This only started happening after I upgraded the app to support Prem channels. Previous app versions before the Prem channels support were great. I don't know if it's related, but it seems like it. I have plenty of band width (396 down and 21 up), all the Apple TVs are hard wired.
When the issue happened last night, as quickly as possible, I submitted the logs via the channels app.
