I have a basic account and it’s few days that in the home of my surveys list I cannot see anymore the default folders neither the one created by me, do someone have the same problem? Could be due to this plan changing?
So long as you have at least the Basic plan, the folders should be visible per this article:
The only account that does not have access to folders is the Free Account. When you say you have Basic, are you referring to the paid Basic license or the Free Account?
