No longer able to change scale ratio on Acrobat Reader

Community Beginner ,
May 09, 2024 May 09, 2024

In the past, when I have wanted to change the scale ratio in Acrobat Reader, I would select the measuring tool and then right-click on my document to get a menu from which I would select "change scale ratio."

Starting this week, the "change scale ratio" option disappeared from the right-click menu. Screenshot below of the menu I get when I right-click.

Is anyone else running into this problem? MacOS Sonoma 14.4.1, Acrobat Reader v2024.002.20736.Change scale ratio gone.png

Try disabling the new (and very buggy) Acrobat UI, via the Options button on the top left corner.

Another option: Create a measurement, then right-click it and see if this option appears in the pop-up menu.

I've had the same problem. It's related to the latest version. Go to File and choose Change to Previous Version (or words to that effect). Do not agree to any future updates.

I'm having the same problem, and running the same OS and same verions of Adobe Acrobat as the OP (Andrew37285438ffmi).  I also do not see "Change to Previous Version" under the File menu.  @David373280485i38 or @Brian37295717y4zh, if you're using MacOS, can you please show us where to find this option?

I use Windows, but I assumed the Adobe Acrobat layout would be the same,
whether you are using MacOS or Windows. For me, the 'Change to Previous
Version (or words to that effect), was in the drop down menu when you click
File (top left hand corner). Another option might be to restore your system
back to a date before the Adobe Acrobat update was installed. Whichever
method works, it's then important that you prevent Adobe Acrobat
automatically updating again, otherwise you'll be back to square one!

Thanks for you suggestion. I was able to find a a button to restore to previous version like you said and can now modify the scale ratio as I was once able to before. Strange for Adobe to make their users rather revert to an older version. That's not right.

The older version of Adobe Acrobat (which I now have) does not appear to
have the option to change back to the previous version.
