I also have a problem with my purchased content from Apple. Florence76, could you please post a link to the answer given for your problem/the related problem instead a link to the person that helped.....turingtest2 has hundreds of posts!
I am unable to stream any purchased content on my iPad Pro, I am unable to view any purchased items in my iTunes library on my Windows 10 computer and on my iPad {only local downloads are visible}. and I get the mentioned error message - problem loading this content - when I try to watch something I have purchased directly from the Apple store on my iPad - on the computer the Play arrow for the iTunes store purchased items just takes me to my Library tab in iTunes {as if to tell me to download the file instead}.
I know how to re-download purchased content. That is not what I want to do. I want to watch purchased items - both TV shows and movies - from the cloud on my devices! I cannot seem to get iTunes to connect to my purchases, either. I want to see my purchases that are in the cloud in my iTunes interface and on my devices. iTunes is updated, and I have signed in and out, checked the View > Purchases/View>Only Downloaded Content options, restarted iTunes and my computer, reset the purchase warnings, checked and changed the date/time on my computer - everything that has been mentioned in dozens of posts about these issues - NOTHING works!
I appreciate any help that can be given beyond what I have already tried.
