Today I was exploring the latest features on the Dynamics 365 CE 2020 Release Wave 2 and I have opened Sales Hub, after sometime I would like to open Customer Service Hub and to my surprise I was not able to find the Icon (check the below screenshot) that used to show the Apps in the system.
After some search, it was replaced with the Hyperlink on the App Names itself.
In simple words, it just returns whatever the first non-null value.
In the same way, we can use Coalecse function in Power Apps formulas as well. Today, I have two variables which has been set from different logics and I had to write the logic to get the not null value between two of them. I used below formula to get the not null value between two variables.
