Thank you, @Gangadhar Ravi !
I was using .svg (and would prefer to keep it that way).
Edited to add: I just tried a .png and it works in the new and old app also. @Gangadhar Ravi , you might want to add that to your post for future users. I'll mark your post as the solution later, after a ServiceNow employee has had the opportunity to see and maybe answer my remaining questions.
If any ServiceNow employees happen by, can you tell why we're going backwards or if there are any plans on fixing this?
.jpg and .gif are the last two image type choices I'd make for mobile due to file size, scalability, and lack of background transparency on the part of .jpg.
If not going to fix it, then will the non-allowed file types be removed from the list of supported file types on the upload page and incorrect file types prevented from uploading?
