For some reason, despite checking that my account automatically accepts incoming collaboration invitations, I haven't received an invite for a folder to collaborate on, and when I click the link to the folder, it says that the content is unavailable to me.

I've checked my spam/junk folders, and there's no invite there, either.

On the collaborator's end, it says that they invited me to the folder, but my account is marked as "Pending."

Are there any workarounds? Any help would be greatly appreciated. Thanks!
