Reduce Icon Size
Toolbar Icons are insanely large. Unable to modify or alter in any way (I've reviewed forums for info, and when I follow steps in "Preferences>General>Scale for screen resolution..." there are no options for me on any of my Windows 10 machines. It's like, cartoonishly large and very distracting.
Apologies for the issue that you are facing with the Acrobat Toolbar icons size.
Could you please check if this is the concern that you are facing only with the last update of Acrobat or is it something that you observe for quite some time previously as well ?
Also, could you please attach a snapshot of what exactly do you face the issue with for icons size ?
