I tried yesterday down two pictures, and recorded distorted ... and I can not download them again, I have to pay again ... No help from Adobe ... What disorder !!! I wish you luck!
Have you tried to reset your browser or clean the cache?
What happens if you try in a different browser?
"Let's say" doesn't show any output where, "Bean Soup" does and the navigation to different pages works as well.
400 page error assuming to be related as Bad Request error- hope this article helps: How can I search Adobe Stock? I get a 400 Bad Request Error message.
If an image is licensed, kindly go to your License History, click on that Image ID and click Save to Computer. This would save that image to your "Downloads" folder.
Reference: Unable to download Adobe Stock images
Hope this helps.
