I can only see the toolbar. Nothing else unless I do ctrl + l.

After days of struggling with this, I clicked on the Adobe icon in the tray at the bottom and saw a small option to maximize and it restored it to full screen and not just the toolbar sliver!  WHEW…  Very frustrating. 

Thank you! I have been trying to figure this out for weeks! usually when I hit the little dot it closed it. I do see in the menu an option to Disable new acrobat.

What the actual F adobe? You pack all these ridiculous AI pieces into the software and someone is too stupid to fix this? It renders your program useless? Someone… get your shit together!

What happened to this program ??  Same issue as the picture above.  No chat with adobe ??? 

Thanks for starting this thread. It’s very time consuming doing some of the work arounds listed. Please fix this.

This worked for me, solution suggestion from Copilot.  I manually added the DWORD in Regedit.

Registry Editor

1. Open regedit
2. Navigate to:
   HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\DC\AVGeneral
3. Create or edit DWORD (32-bit) value: bEnableAV2
4. Set it to 0
5. Restart Acrobat

PowerShell

Set-ItemProperty -Path "HKCU:\Software\Adobe\Adobe Acrobat\DC\AVGeneral" -Name "bEnableAV2" -Type DWord -Value 0

• This key applies to Acrobat DC (Pro/Standard).
• Reader uses the same key under the Reader path.
• If the key doesn’t exist, Acrobat defaults to the new UI, so you must create it.

Had to disable ‘New Acrobat’ as well as this kept happening when opening new documents. None of the suggestions such as Ctrt-L or right-click worked - right-click didn’t have a resize or maximise option. Only thing that works is resizing the stupid tiny circle (what is that about? user friendly NOT) except one time I couldn’t see it because of split screen - had to change monitor resolution to fix. Very frustrating.

Has anyone tried uninstalling the latest update? I cannot work like this. I need to have multiple documents open at once and I barely get one opened and it is so slow. Between the ridiculous AI tools dragging it down, now I can’t even open a PDF without it taking up my entire screen?! This is NOT user friendly. The work arounds do work, but why am I using a work around to be able to open a document. You have one job Adobe, let us open documents...that’s it! 

I am having this same issue and it is insane that Adobe unleasehd this “update?”  on its users. The only fix for me has been to hover over Acrobat icon and rightclick the document name, then hit “maximize”

I completely agree with the other comments here. The new Acrobat interface is extremely frustrating and unintuitive.

It was unnecessarily difficult to open a document. The floating toolbar behavior caused the program to appear broken, and in many cases I was left with only the tools panel visible and no document window. Clicking slightly off-target often minimized or closed the program entirely. On larger or ultra-wide monitors, the window behavior is especially problematic.

If a user has a typical, cluttered desktop, the interface increases the likelihood of accidentally opening the wrong file or closing the intended one. The workflow that used to be simple and predictable is now disruptive and inefficient.

Disabling the “New Acrobat” experience immediately resolved these issues. That alone suggests the redesign introduced usability problems that were not present in the classic interface.

Acrobat is a strong product. It does not need dramatic interface overhauls. Incremental improvements to stability and workflow would be far more valuable than a complete UI redesign that impairs usability.

Please prioritize functionality and user experience over visual redesign.
