Sorry, i’ve been so busy lately..
If the email address did not match with your email addresss of your google drive, it will be hidden from the google drive default interface.
The email address is exactly the same in the plugin, in the API account and my account yet it still does not show. I appear to not only be the only one with this problem.
Having the exact same issue with a Google Apps account.
Unfortunately it appears the developer has abandoned us so I wouldn’t hold out any hope for a fix.
Also having the same issue with a gmail account.
I had the same problem but I figured it out. The way I got it to show up in my “incoming” folder was by deleting the first one I made. I then got the option to create a new folder, which then did show up in my incoming dropbox folder. Just make sure the email address in the settings is the address you want to initially share the folder with. From there on in, you can add subfolders in there and the plugin picks em’ up.
If the problem still exists, you can try to regenerate a new google drive api key and replace the api key with the new one
