I get the feeling this might be the usual Redmond half-baked "Agile / Scrum mess". Not being able to multi-parent and create a hierarchy deeper than one means 99% of real world business requirements aren't deliverable.
So we'll have to wait a another couple of years before v2.0 comes out - like everything else from the MS development teams.
It's sad when you find yourself heading for the user voice to post up the shortcomings of a "new" product and it isn't even live in your tenancy yet.
I say "new" product because, I mean, how "new" is a hierarchy grouper / structurer product concept? We were using folders from the year dot. Why all this triumphant hub-bubba nonsense from the MVP Redmond brown-nosers about something that's been around for years and has just made it into DespairPoint after twenty years - and is still half-baked?
