Looks like, this issue still persists...
In my use case:
In the Menu Widget, there's an option to choose Device Selector as Target.
But the menu items don't update with Device Selector, as Target.
Upon choosing a specific Device itself, menu items update as expected.
Blynk.setProperty(V11, "labels", "New Item 1", "New Item 2", "New Item 3");
I assign Virtual Pin
V0 to a Button and the items update at Button Press
Choosing a specific device as Target: Works
Choosing Device Selector as Target: Doesn't Work
