Is Shift Click no longer supported while using the Remove tools?

@ObservationsInTime 

For Remove (Gen AI and Object Aware both off), Heal and Clone, Click followed by Shift+Click still connects the first spot to the second with a straight line so long as you don't change the Brush size before the Shift+Click. Changing the Brush size deselects the first spot. It's a bug and hopefully, it will be fixed in a future update.

Here is a work around for drawing connected lines while varying Brush size between Shift+Clicks. In Remove mode, add the first spot with a Click, then choose Refine. You can now add a second spot using Shift+Click to draw a connecting line and resize the Brush as much as you like. Click Apply when you're done. While the Pin is still active, you can then change the Remove to a Heal or Clone by clicking the appropriate tool icon.

In my LR 13.3.1 / Mac OS 14.5, using shift-click to draw a straight brush stroke from the previous click still works, EXCEPT when you have Object Aware selected. 

When Object Aware is selected, you get one chance to brush the object you want to be automatically selected -- click down, brush the objected, click up, and the object is automatically identified.  After that, you can refine the selection with Add and Subtract applying more brush strokes, including shift-clicked straight lines, but those refinements won't be using Object Aware to guess the object automatically.

Shift+click+drag using Clone, Heal, Remove all constrain the drag to vertical or horozontal on my Windows/10,  LrC/13.3.1 system

As far as I know shift-click should still work. I can't check it right now because I type this on my iPad. There is a known issue that the brush size and the actual mask it creates are different initially however. Perhaps that is what causes this.
