Hi @Max Foerster - K15t
I suppose you could help me 
I'm trying out the Sum up in our DC instance.
And it is working great.
But, when I try to show the total SP's on my kanban or Scrum board, I get the errors:
"Calculation rule could not be changed. Please refresh to see the current status."
Do you (or somebody else) know what the cause could be?
My Calculation rule.

Thx in advance.
