You’re right. Those two models do have the same casing. I checked…after looking for a magnifying glass and a flashlight!…and I have model A1378. So it looks like I have Apple TV 2nd gen, and need to use Airplay.
I tried again last evening to get AirPlay to work, but no luck.
Also tried again just now. Screen mirroring works. I can see myself typing this on the TV screen.
I pressed the Apple TV+ app on my iPad and Choose Ted Lasso, Play First Episode.
Got a quick message that “The video is now playing on Apple TV” and then immediately the message switched to:
“There is a problem loading this content.”
So I then clicked on another video and got the same error message.
What other info do you need to help me to get this to work?
