Bug description :

When I tried to upload my entire library of photos and videos, only some videos got uploaded. All photos and most videos were added to the transfer queue, then removed from the queue without being sent (the “upload” tab stayed empty with the message telling it was empty), and without any error popping up, neither on the server (logs empty) or the app.

I did try to restart the app, reset it, restart the phone, even the server, nothing changed at all. Thankfully I didn’t check “remove from library after upload” or I’d have lost all my photos.

Joined 2 screenshots taken a few seconds apart. You can see that the queued files count decreased from 2808 but both the error and uploading tabs stayed empty.

I really have no idea what’s going on.

and when did it stop, just after a few files, after the phone was locked again?

Did you try to take a new photo, does it sync again, or trigger to continue the sync? If there is still a queue, there should be a way that it continues…

And do you use the option to only upload on Wifi connections? Then perhaps enabling/disabling wifi …
