Canvas area not active for drag and drop
Service Studio Version
11.10.21 (Build 41765)

I started the DataRelationshipsExcercise and  the canvas area isn't allowing me to drop an Entity. 

 The left side tools are inactive as well.


In order to drop the Entity, you have to first go to one of your Screens or, Server Actions or Aggregates in the Interface or Logic tabs according to the what the PDF's exercise, otherwise Service Studio will not recognize what you are trying to do by just drag and dropping an Entity.

Try exiting that "empty" state by double clicking on a Screen, Server Action, Entity Diagram or Aggregate before drag and dropping the Entity and it should work as expected, let me know if that helps.
