I'm mounting my remote proton (Proton Drive, newcomer on rclone), with:
rclone mount --dir-cache-time=1000h --vfs-cache-mode=full --vfs-cache-max-size=150G --vfs-cache-max-age=12h --vfs-fast-fingerprint proton:SomeFolder ~/SomeFolder &
It mounts without problem, but the sync only goes one way: what I do in my local folder is immediately pushed to my browser's drive.proton.me, but nothing (creation, deletion, modification) I do on my cloud goes back down to my mounted folder...
So in summary local → cloud syncs well,
but there is no cloud → local sync at all.
Back to the starting point. I found the behaviour of setting small intervals for --dir-cache-time very unreliable; what's more, I need a fast browsing so I think I need to stick with a high value for this flag (I put 1000h).
However, my problem is back:
Any file/folder created, either on my local mount, Android app or web browser, is almost instantaneously mirrored on the others;
but... any file/folder deleted from any of these services does not get deleted on the others, and stay there forever.
If I could solve this I'd be the happiest man on Earth, because it would mean I could work directly into a mounted rclone of my Proton Drive.
