Marginnote lost all my categories ! please help!

In trying to migrating from marginote 2 to 3, I lost all my categories!!!

How did this happen?

In the mean-time, I still can’t validate my original 2 purchase in order to upgrade to 3 on my mac. This is very disappointing.

You may want to see if you’re looking at folders instead of categories.

The migration only works for document categories.
