Embarassing Tutorial Window

Hello,

I downloaded Adobe Dimension a few hours ago and just started using it.

There seems to be a problem for me while I'm trying to use the in-app tutorial. The tutorial is set in a white window that appears right over the work area. I can't move this window, so I cannot see what I am doing with the software.

Here is a screenshot

Is it normal ?

Maybe, it will be useful to the Adobe developpers.
