Had to drag PDF's into the window. Couldn't do the folder or parent folders.

I've encountered this bug as well. I figured it was a problem with my folder structure or something.
Thanks for reporting. I'm curious what OS and Browser are you using? We will test further on our end.
For me: Win11Pro 24H2 (OS Build 26100.6584) and Edge Version 140.0.3485.66 (Official build) (64-bit). Also not working on Chrome Version 140.0.7339.186 (Official Build) (64-bit)
Happens to me as well on Chrome
We just released a patch. Is it working properly for you now?
Seems to be working on Chrome and Edge here. Thanks Heber!
I am using Mozilla - and yes it seems to be working now! Thank you
