I know that might sound strange but I can't create independent section groups inside one notebook. Every time I create new section group it's created inside existing section group but not as independent one. How can I create several independent section groups inside one notebook?
I am on the desktop client on a Windows10 machine. When I right click in the gray area it allows me to create a new section or new section group. You can see that I added 3 individual section groups all at the top level.
Be sure you are all the way at the top level, and not inside of an existing section group.
If you are able to provide the steps you are taking and maybe a screenshot that could help as well.
