Hello,
I'm also looking for a successor of RoboForm and just followed your steps successfully.
Unfortunately Enpass does not consider the folder structure of RoboForm - I RF have hundreds of Logins saved in folders, all objects are now un-categorized.
For example in RF there's a folder named "E-Mail" and a login named "name@emailprovider.com", in Enpass it's saved as "E-Mail\name@emailprovider.com".
Apart from the fact that importing from RF with Enpass 6 still does not work, in my opinion it should not be problem to import logins from RF considering the folder structure (import RF folders to Enpass categories).
