I’m now in the same boat. I’ve purchased quite a few of your books over the years and thought the subscription was a great idea… only to find that I can’t download ePubs of the books I want to read. Nor, it would seem, can I even purchase the book!
Now I’m stuck. Access to the videos requires a subscription, but subscriptions prevent me from downloading books to read offline on my iPad Pro. And iPad reading was what attracted me to your offerings in the first place!
I get that you basically don’t want subscribers to download everything and then quit, but this change really screws over your long time customers.
I suggest that you strongly consider allowing customers to be able to download books, perhaps limiting them to one a month or something like that. As is, I’m probably going to seriously reconsider my subscription plan.
