Finally had the opportunity to attempt @absethi's proposed workaround. I installed the 11GB XCode application to be able to edit the .plist file. I added the "HonorSystemScrollerPref" as indicated in the attached screenshot.

It restores the scroll bars for navigating around a single page, if you're zoomed in enough that an entire page does not fit on the screen.

For navigating around a multi-page document, it restores the white bars where the scroll bars should be, but they are completely empty. There is no visual indication of how far through the document you are except the raw page number.

Please return this functionality for large documents.

I have a workaround for the moment. It seems to be there is no possibility to show scroll bars always.
My settings are.
mac OS: Scroll bars = always
Acrobat: Touchscreen mode = never

If scroll bars are disappeared and I need them I do following.
1. Hide Acrobat by pressing [OPTION] and click with mouse on FINDER
2. Bring back Acrobat with [COMMAND] [TAB]
Hope it help til Adobe brings an Update for this problem.

"f you toggle the setting in macOS system settings to another option and then back to "Always", the scroll bar shows up."
I was using this as a method to get a temporary scroll bar in Acrobat. But over the last few days, this functionality has disappeared, and now I cannot get a scrollbar in Acrobat unless I scroll with the trackpad.

Processor: Apple M1

Same experience as the original poster. Over the last few days, I am also not able to bring back the scroll bar temporarily by changing the macOS System Settings to "Show scroll bar" -> "Always".
I would like to point out that Microsoft and other apps are able to honour MacOS Scroll Framework. In fact, Adobe manages this fine with Illustrator, so why not with Acrobat?
Please Adobe, post some assistance for how to get the settings correct - it is making my work difficult!

Have to agree with Brandon's & Jacob's messages below.
In the complicated reply to this thread, didn't make such since, as there was no idea of what if any program on my Mac I should try and use let alone edit this .plist file!?
I downgraded to an earlier version of DC (from the latest Pro version) after this recent upgrade (downgrade!), and as Jacob mentioned will this manual 'fix' get overwritten the next time the next sub-version comes out?
If so, are you expecting users that actually need (due to their disabilities) the old, usable scroll bars to have to manually edit your software that we are actually paying for?
Please, just bring back the scrollbar, well at least make them visible for, 1) longer before ghosting away, or 2) make the white block on a white background viewable again... I just can't understand how the current version is in anyway an upgrade? from what WAS the BEST pdf tool available

absethi's workaround DOES appear to work for me.

My questions now are, how long will this last until it's overwritten, and why is this required? Why can't here be a setting added to honor the system scroll bar settings?

I can't ask my users to edit plist files to get this feature back, that's unrealistic.

@absethi
I added the lines with the Xcode Editor.
After launching Acrobat Pro the scroll bar is not appearing.
If I close Acrobat and open the plist in Xcode again the lines are deleted.

Absethi, those instructions don't make any sense to me, and the image looks nothing like what the com.adobe.Acrobat.Pro.plist file looks like when I open it in a text editor. Please provide clearer step-by-step instructions to make the scroll bar appear, especially for mac users.

Hi,

We acknowledge your concerns and thank you for your feedback.
The changes for Scroll have been done for Scroll Framework update in the recommendation from Mac OS. The Scroll Bar will now be available when scrolling.

If you want to see scroll bars always, we do have a working solution for that.
For that, we will be honouring the macOS setting.

- you will have to change the Mac setting to Always show the scroll bar
- you will have to set below plist registry

Steps-
- Go to ~/Library/Preferences/ -> open com.adobe.Acrobat.Pro.plist
- Go to DC -> AVGeneral & create plist key -> HonorSystemScrollerPref as shown in the attached image.

- Run the below command in the terminal.
sudo killall cfprefsd

Thanks,
Abhinav Sethi

Adding a preference in the Adobe Acrobat Application would be very beneficial for my users as I've had multiple requests for the option to have the scroll bar remain on the screen indefinitely.

Also reproducible on Intel:
Architecture: x86_64
Processor: Intel
Build: 23.6.20320.0
AGM: 7.1.1
CoolType: 8.3.1
JP2K: 4.0.0.52671

I am using a Wacom Pen instead a mouse. I need the show always support, because the pen will not recognized like a mouse and the scroll bars never appear.
My Mac settings is set to allways and the settings in Acrobat for touch mode is set to never.
The only way to show scroll bars is to launch Acrobat switch to Mac settings disable scroll bars allways and turn on again. Now the scroll bars appears in Acrobat. After a restart of Acrobat the scroll bars are disabled again
