In Adobe Acrobat Pro software, view controls fail after merging 3DPDF

Hi  there

Hope you are doing well and thanks for reaching out.

What is the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 23.08.20555 installed. Go to Help > Check for updates and reboot the computer once.
 
Also try to repair the installation from the help menu (Win Only) and see if that works.
 
Please try to reset the Acrobat preferences as described here https://adobe.ly/4a5ZAPY
