Apple TV audio/video sync issues

Lately I’ve been having difficulty with lagging audio to video syncing with my Apple TV 4K. If I restart it, the problem is temporarily fixed, but after about 5 minutes of watching Netflix or hbo now, the audio will start lagging. This doesn’t typically occur with Disney plus or streaming movies from iTunes. Once the audio starts to lag with the service, it continues to lag once I exit the app. The sounds you hear when hovering over different apps lags significantly. Again, this is only fixed by resetting the Apple TV. I have run Netflix through my (smart) TV and had no problems with audio (it’s the same TV I have the Apple TV connected to). I’ve also ensured my internet connection/speed is good (>300Mbs), and have tried connecting my Apple TV to my router via Ethernet cable, with no improvement. This problem has been present for months but has gotten significantly worse recently. Changing between audio formats doesn’t do anything (a suggestion I saw when researching the topic). Please help.

I just updated my Apple TV 4K and this same thing started happening to me today. Watched two Netfix movies last night with no issues, but tonight the sound streams to my airplay Bose speakers ahead of the video. Also, my picture is slightly glitchy. When I change to TV speaker (which runs through HDMI cable) sound is perfectly synced with video and no more glitch. Again, this was NOT an issue until my Apple TV updated. This doesn't look like a fluke. It looks like a BAD UPGRADE. PLEASE FIX ASAP!
