Proton Drive on macOS is completely broken. It fails to present file path entries in Finder for files I've long since uploaded to my Proton Drive account from other devices.

As a workaround, I have to move a recent file from Proton Drive to my Mac, pause syncing, resume syncing, and wait for the next file entry to appear. I have to do this for every single missing entry, which is quite laborious. Computers exist to automate, not cause even more problems.
