When I back up photos to ProtonDrive, they don't sync with the desktop app, so I can't use or view them locally on my PC or Mac.

I would like to be able to synchronize the photos I have backed up to Photo with my PC or Mac folders. It's a pain to have to move and copy them manually.

I have to view them online every time, and it takes a long time for thumbnails to display, which is very inconvenient. Thumbnails are cached to a certain extent, but even those cached thumbnails are slow to display.
