I am more than a little disappointed that I can’t download a significant number of rented movies (the 4K ones) from iTunes onto my iPad Pro. I understand that 4K movies take up a huge amount of space, but Apple doesn’t offer standard HD versions of many of its newer titles. Streaming works fine in my home, but I do a lot of traveling and want to be able to download and then watch rented movies on an airplane. Does anyone have suggestions on how to deal with this problem?
