Cannot download media just purchased due to Apple ID issue
For the past couple weeks, I have had problems where I purchase media (songs or TV shows), but can then not download it, getting this error:
The error has shown with TV shows purchased mere seconds before on the same laptop, or with songs purchased on one authorized laptop and shows when I try to download on the one where I keep my library. I can download the same media on that other laptop and on my iPad, only the MacBook Air is being a problem.
OS is latest Mojave -- have not upgraded to Catalina.
Have deauthed and reauthed the laptop; no change.
My iTunes library is stored on an external drive, but it is connected.
Does not apply to all media. About 3/4 of the purchases download fine, even done minutes apart.
Issue has been occurring roughly since October 1.
