We have several users reporting the same problem and they are getting stuck.
We have two drop-downs:
The Month is linked to the Tenant. I.e. only months available within the given tenant are shown in the dropdown.
If Tenant A has January, February, and Tenant B only has March, then after changing from Tenant B to Tenant A, will show Tenant A + March (month not available within Tenant A) combo in the drop-down, and “No Data” in the visual.
