kio-gdrive hangs on loading in dolphin

Hi, on my laptop TUXEDO InfinityBook Pro 15 v4, ssd disk=2Tb, /home EXT3 partition=58Gb, processor= Intel Core i7-8565U, RAM=32Gb, graphics card Model: “Intel UHD Graphics 620 (Whiskey Lake)” with tri boot leap 15.3, leap 15.3, windows 10 running KDE plasma,
I installed kio-gdrive version 21.08.1-lp153.48.2, in system settings>on line account I created a google account connected to my gdrive account, I can see in dolphin(version 21.08.1)>network>gdrive:/google-myaccount, click on it but it hangs on loading, it means that the dolphin window is white and wit written “Loading…”.
how can I have my googledrive working on dolphin?

May be wrong but as I recall google drive does not support BTRFS file system. Has that been fixed lately???

I haven’t BTRFS on my laptop, I have EXT4 and NTFS

using the new version 21.08.2-lp153.49.2 no news, always it hangs on loading:|

IS the "shared directory on ext4/3 or NTFS??? Previous post not clear.

I didn’t know that there should be a shared directory, how can I check where it is?

I tried systemsettings>online accounts>account detail but no informations is given, only change the name…
