Planner - Failed to create plan
When I try to create a Planner tab I keep getting the message "Failed to create plan"
This seems to be a problem where planner is looking at members only and not owners. To add planner requires adding the Teams owners to the Teams Members group.

Same here -- this just started happening -- what changed? We use a template when provisioning our team sites and this was working just fine.
Issue happens from time to time. You can solve it with this workaround:
remove member/owner from Team and add him/her again. Now it works perfectly.
This has been happening since last week for us..
Same issue for me.
