"So I will select a portion of a drawing > Transform Selection and try
scaling or rotating but its just moving around an empty selection marquee.
The drawing doesn’t change."

I agree that there is a disconnect between what you are trying to say and what we are hearing. One issue that I see is that in this sentence you say that Transform Selection is not working because the drawing does not change. It's not supposed to change. Only the marching ants (selection marquee) will change as in the image below. In Photoshop for Desktop, this command is in the Selection menu.

"There are 2 ways to activate the transform tool, one is through the tool bar, and the other is "... more" at the bottom which takes you to transform selection as well which is typically how I'd access the transform tool but no longer works."
The other thing I see is that you say there are two ways to activate the Transform tool. That is not true, as these are two different tools that do different things.
- The Scale and Rotate tool (in the toolbar on the left and circled earlier) will transform the pixels, or "drawing" in your words. It is equivalent to Edit > Free Transform.
- The Transform Selection tool from the Heads Up Display (HUD) will transform the marching ants. It is equivalent to Select > Transform Selection.
