Seadrive can't find shared folder

Hi, as a previoiusly satisfied user of the older Seafile client for Windows I have a new Windows 10 computer and am now apparently forced to use Seadrive 3.0.11, which makes me unable to do my work. For my job I have to edit and save files in a subfolder in the ‘shared with groups’ category in the web browser interface. The new Seadrive app gives me no way of accessing these files and editing them locally. If I look under the Windows folder ‘Seadrive root’ (where all my other libraries are stored) the most logical place to look for such files is a folder that would translate as something like ‘for my groups’ (on my German machine it is ‘für meine Gruppen’). If I open that folder there is nothing in it, although the ‘shared with groups’ folder in the browser interface has folders in it. I can find no other place where these folders could be accessed using the Seadrive client. This is a problem since the Seafile browser interfact doesn’t allow me to work on these files online (e.g. I have to edit rtf files but these won’t display online). I installed Seadrive yesterday, so I don’t know if reinstalling it is going to help.
Is there a solution here? If there isn’t I guess I’ll have to see if I can download the old Seafile client, which was in some ways preferable to the new Seadrive (since I could actually select which files and folders I wanted to save and edit locally and had more control over the settings). I guess Seafile doesn’t want people to use the old client, since it is not mentioned prominently as an option on the download page.
Thanks for any suggestions,
Andrew

If the folder is shared to you both personally and from a group, the folder would only appears in the “Shared with me” category folder. Is this your case? Another reason would be that the folder is shared to you in “cloud only” permissions, which prevents it from syncing to your computer.
