the upscaling is not allways working
the view on folder is not working

What’s happening when you’re upscaling? I’ll need more information on what’s happening here to assist.

It will freeze at the same value and will not change to X4 or 5 or 3 or any number not even DPI.
not for every image and not all the time.

How odd. Could you reach out to Support for further troubleshooting on this?
