Lately many JPG files will not open and display the error "File type is not supported"

Lately (over the past couple of months or so) I have been having a problem viewing some JPG files on my My Cloud Home iOS app. These are images that I am absolutely certain used to open just fine.
I can see the thumbnail but when I tap on it I get that error screen.
If I tap the 3 dots and save it to my camera roll I can view it there just fine.
These are JPG files, not HEIC or anything like that.
I tried it on both my iPhone 11 and my iPad Pro, both running the latest firmware (13.7)
My Cloud Home app version is 4.10.0 (1751)
The device software version is 7.9.2-103

What could have happened to cause this?

Changing the file extension from JPG to jpg (i.e. lowercase) worked for me.
