So to keep you updated, if you're interested, I tried today and it still didn't work, the green bar that shows the progress never moves/changes size and the folders get created(they even claim to have the correct number of items inside them) but when you do open them up they are empty.
I even made a video like promised, but I forgot how annyoing/complicated(in my situation anyway) it is to get the video from my quest to the pc so I can share it with you, and I eventually got totally fed up with all of it and decided to just sell my quest.
Anyways thank you for all your hard work, other then the fact that it can't seem to backup stuff either, you app has been great and I hope to see you again on the Quest 4 which I will definitely check out especially if it will have eyetracking like the rumous suggest.
Till then, have a good one.
