iPhone "Unable to Download Episode" and "There’s a problem loading this content" errors on Apple TV app.

In the Apple TV app on my iPhone 14 Pro Max. In a SpongeBob SquarePants episode that was purchased recently, the video stops randomly and a "There was a problem loading this content." message comes up sometime during the episode. Also, when attempting to download some episodes of SpongeBob SquarePants on the iPhone, it stops downloading after it just started, and a "Unable to Download Episode" message comes up each time. I tried a few things, like changing some of the Apple TV settings, resetting the iPhone, reopening the app after closing it, to no avail. No idea whether that is just a bug in the app itself or not.

Any suggestions about a possible fix for these issues?

thanks.
