@Grim_Echo Having also an issue here: Does not keep Team Drive sub folders in sync since several weeks on Ubuntu 18.10
The support team does respond, but usually with a delay of several days. Their last email is not very comforting. It indicates that they are focusing on rebuilding the product from ground up and have not yet even determined since which version my reported bug appeared.
Tried downgrading to several older versions but no change in behavior. My fear is that downgrading requires not only finding a version that behaves correctly but also removing all accounts and starting fresh (which in my case is a really pain in the a%% as I currently have no idea which files are local only and which are in my online drive only).
Seeing you are asking for an update in a thread that was opened in Dec 2018 is not inspiring confidence in having any solution soon.
