We have a new Dynamics 365 instance into which we have migrated an 8.2 solution.
We have just discovered that the "Close as Won" button is not working at all. "Close as Lost" is working.
I did get it work on the grid view of opportunities.
Is this likely to be a configuration issue or do we maybe have some code which is interfering?
I wonder if we might have interfered with the ribbon.
As far as I am aware it should just be calling the standard MS functionality.
