Apple TV app, Apple TV+ now available on compatible 2019 LG TVs
LG on Monday announced select 2019 smart TVs now benefit from integration with the Apple TV app and Apple TV+ service, with availability rolling out in the U.S. and more than 80 other countries.

The Korean tech company touted the new capability in a press release, saying owners of compatible televisions can access the app and corresponding streaming service via the LG Home Launcher.
Like previous Apple TV app integrations, including select Roku devices, LG TV owners are able to subscribe to Apple TV Channels, browse an existing iTunes video library and buy or rent shows through the native app. Apple TV+ access enables streaming of Apple's original series and specials.
While a complete list of supported hardware was not provided, the company notes all 2019 OLED TVs and NanoCell TVs (series SM9X and SM8X) now Apple technologies including Apple TV, AirPlay 2 and HomeKit. LG announced plans to Integrate AirPlay 2 and HomeKit last July, and subsequently rolled out the feature as part of a software update issued later that month.
LG plans to bake the Apple TV app into select UHD TVs (series UM7X and UM6X) in February, while both the app and Apple TV+ will be made available on 2018 model year TVs later this year through an over-the-air firmware release.
Today's news arrives almost a month after LG at CES said the Apple TV app and Apple TV+ would arrive on 2020 model year smart TVs.

The same issue is not reproducible in any of the other apps, like Netflix. Solution so far: plug the HDMI cable on my MBP to watch Apple TV+ content.
That’s odd, I have 3rd and 4th generation Apple TV’s. I watch tv+ on both without any issues.
Does it correct itself after a stop, then resume?
It almost sounds like one of the AV components in the chain is reporting a capability that it doesn't properly support. Like some particular audio format which ATV+ uses that those other apps don't. Might want to play around with the ATV output formats (video & audio) to see if that helps.
