I’m using an AppleTV HD with Peacock and it’s pretty bad. I wouldn’t consider NBC a niche service. After an episode ends, I need to wait for the new one to start to be sure it marks the last one as watched. When going back to the main screen, it can take upwards of 30 seconds, maybe more (it feels like an eternity), for the “watch next” to update. If I don’t wait for it to update, it will start playing an old episode the next time I try to launch it. This lag also persists over app switching. So if I stop watching a show, switch to something else for a while, then go back to Peacock and quickly go into the series I was watching, it will play old stuff.
Even switching between 2 series in my currently watching list can take an exceedingly long time. Sometimes I try to switch back and forth to force and update and it feels like I’m back on 56K.
The Apple TV HD is old, technically legacy, but still supports tvOS 26. I have an Apple TV 4K in the house as well, which I’ve been meaning to migrate to, to see if it’s any better. But the HD works fine for pretty much everything else. Peacock as a service seems to have an extreme amount of lag.
Sounds just like a poorly written app. I'm surprised Apple doesn't enforce stricter performance guidelines.
On an older Roku Ultra Peacock also isn't great but not nearly as bad as you describe - maybe they just ported over their Roku version somehow and it has horrible Apple TV performance.
Anecdotally I have heard the newer Nvidia Shields to be very fast
If you think Peackock is bad, try Paramount+, it's an impressively bad app that, along with being very laggy, will crash fairly regularly too.
Pretty much every streaming app I use (not just on AppleTV) has a hard time remembering where I left off. I now have the habit of skipping through the credits and letting the app play the last 8 seconds and close the episode itself, in the perhaps misguided hope that then it will remember I've played the episode.
It sounds like an older version of the app. I used to see all kinds of similar issues with Peacock on my Apple 4k device. NBC has put work in to make the app better over the years unlike say, Paramount+. I would check to see if you can manually update the app or try the 4k device and see if it works better. It could be the older chip and more limited memory of the HD device are hitting up against their limits too.
Yes I think the device itself is fine, but the Apple TV apps are mostly terrible and often very laggy/poorly written.
The way developers use the UI toolkit that the Apple TV provides also seems to tend towards apps where it's very difficult to figure out what's the active selection, which is of course _the_ critical challenge.
