Almost every time I watch an apple fitness plus workout on my Apple TV (latest model), the audio goes out of sync after about 10 seconds. Restarting the workout once or twice usually resolves the issue, but it only affects Apple fitness plus streaming. All other streaming apps work fine. The audio is being routed through an original HomePod
Apple TV 4K, tvOS 15
