I am on the Block Breaker section of the Unity 2D course and am trying to select multiple blocks in the scene using shift or ctrl (as clearly demonstrated in the video tutorial) However, whenever I click on a second block, Canvas is highlighted instead. I tried the suggestion in the following forum:
I created another layer by duplicating the Main Camera, locking it, and then moving the Canvas under that. It still selects the canvas, even though it is locked.
I upgraded from 2019.4.17f1 to 2020.2.1f1 hoping that this would fix the problem. However, it does not. Any suggestions are greatly appreciated.
