suddenly Pro for consumers :Group workspace

I have a Pro-licence and use a group workspace to collaborate with my IT collegues.

We share the dashboards from this group with Free users.

This worked fine until today!

Now they get the advice to go PRO.

This is really anoying as we need the groups to work together and as backup. But if we have to buy licences for all our endusers, my company will not be happy to support this nice product :( !
