Disabled creating group, now members / owners can't add planner to existing groups

[Anders Thunem]

I've disabled the option to create new groups.

https://docs.microsoft.com/nb-no/office365/admin/create-groups/manage-creation-of-groups?view=o365-w...

But now owners / members can't add a planner to existing groups. This worked before!

Info:

I've created a provisioning template that creates groups.

I believe this is a bug / lack of functionality....only users allowed to create Groups will be able to create Planner Plans something that does not make sense in the scenario you have just described
