@luisadrvieira Thanks, I checked and indeed Drag & Drop works fine for Folder's. Thanks again. But this bug needs to be resolved by Opera for not all use Drag & Drop and can then be diverted to use Chrome or Firefox

Much Lighter and better than ADGuard (used for 2 yrs).
Love this extension.
Works on YouTube.
Keep up the Good Work.

@pyll0 Happened to me also in Ubuntu Linux, had to revert back to Opera 98

Ubuntu, Opera 96, unable to upload Folders in "Google Drive" & "One Drive"

No upload confirmation on Top

Google Drive gives error
/home/getafix/Pictures/Screenshots/gdrive error.png

One Drive tries upload but nothing happens

Firefox & Google Chrome work fine on Ubuntu Linux

My Opera version is 96

Same issue being faced, getting on nerves now.
