Well, recently Google broke our drive access and requires kio-gdrive to pass through some verification to prove to google, it passes its criteria:
Google requires kio-gdrive to pass through those hoops yearly.
And note kio-gdrive has no active maintainer.
Still efforts are underway. That takes place over the kde-devel mailing-list. No time-frame, this is done on the free time of community member.
This might get fixed, but it is still a pain to go through…
