Can't create Level Variant Sets Asset

I’ve checked Variant Manager Plugin and restarted UE4 Editor several times, but Istill can’t create a Level Variant Sets Asset.

Did you find the solution to this? I have the same problem.

No, unfortunately not

Where you using Unreal Studio? Because I figured out the Variant Manager works only inside of it.
I should’ve figured it out sooner, since it is listed into the Unreal Studio category in the Plugins window.
