On a gallery or form you get a message 'no datasource connected yet'. There are some issues with this warning.
Is still there when you connect to a collection
Can't be turned off.
Please fix for 1 and add a setting for 2, with which you can turn individual warnings off.
@Audrie-MSFT, would you be so kind to address this to the right person at your side. It's a bit irritating that I can't see the controls because off this warnings, as you can see in the picture attached . Thanks Paul
