I have been usinng Adobe Express for two weeks to remove background and download these. No problem. Just drag and drop or search on my device. Now, I click download and receive a black page. Even when it opens to my projects it is a black page. Any suggestions? I also have Photoshop 2020, and can't remove these without hours of refining them, so if there is this quick removal in PS, I would love to know it.
Sorry to hear about your difficulties. Are you working from a computer or mobile device?
I'd start with these and see if they help
