I have the desktop app downloaded but it just endlessly spins with the logo on a white page. I tried opening in both chrome and firefox (never signed into so cache or cookies shouldn't be an issue) and the same thing happens. I haven't saved the file or exported my collection recently so I am hoping there is an easy fix!

It is working here ;) can you try to clean your cache (f12/applications) ?
