P: Doesn't constrain proportions when resizing from side handle while holding Shift key

I just spent 20 minutes trying to resize and object in PS 20.0. I could not proportionally scale a placed image. Spent another 10 minutes searching google, trying to figure how to not to bring up old versions of photoshop for the answer. I land here, and the answer is "don't hold shift".

"Don't hold shift" anymore?

WUT?

I have to unlearn how many decades of muscle memory?

THANKS, ALEJANDRO! 
I just signed up to thank you in person! I was mad already!

For the love of god, don't fix things that ain't broken. Truly mind-numbing nonsense sorry.

Thanks, Captain Obvious!

This is the official response from Adobe: new feature, use Shift to *un* constrain.  Constrain to fixed aspect is now on by default.  

In other words, you don't need to press Shift to constrain proportions, just drag any corner to the size you want.

I have a feeling maybe two people requested this.

Adobe seems to want to make all the shortcuts and functions/commands work the same across the creative cloud universe, but mostly so far it's been photoshop getting the butt of changes in that regard.. It's like adobe is saying we don't care about the way photoshop has worked since 1990, it must work like InDesign or Illustrator or some other creative clound app. No body ever complained on the adobe forums for more than 20 yrs and all of a sudden it's one of the most requested features, really?

All that being said the feature doesn't even work as advertised anyway, so i reverted all our machines back as soon as the workaround posted by ryze was available.

Here's a clue to the bug. When in Transform Mode click on the Maintain aspect ratio button in the tool options bar and be led down the path of transform run amuck..


Now if adobe would only allow us the same pleasure with that god awful Auto-commit.


For anybody who wants to revert back to the old faithful way of doing things, this is the method to do so from John McAssey in the https://feedback.photoshop.com/photoshop_family/topics/constrained-resize-ps-cc-20 thread:

To revert to the legacy transform behavior, do the following:

1. Use Notepad (Windows) or a text editor on Mac OS to create a plain text file (.txt).
2. Type the text below in the text file:
   
   TransformProportionalScale 0
   
   
3. Save the file as "PSUserConfig.txt" to your Photoshop settings folder:
   • Windows: [Installation Drive]:\Users\[User Name]\AppData\Roaming\Adobe\Adobe Photoshop CC 2019\Adobe Photoshop CC 2019 Settings\
   • macOS: //Users/[User Name]/Library/Preferences/Adobe Photoshop CC 2019 Settings/

Was this actually a 'feature' people were requesting? One of the most oft used shortcuts in Photoshop now has to be 'forgotten'...and not only does that combo not work, but Alt + Shift to scale from center has also been lost because of it. How are we supposed to scale proportionately from center without messing with anchor points now? 1 step forward, 2 steps back...

So how do we disable this? It borders on foolishness to approach this in the way Adobe has. NO ONE would intuitively do this. It's too late for people to re-learn one of the MOST BASIC FEATURES of Photoshop. Insanity.
