Fix Disappearing Quick Tools
I see where others had this issue in previous versions, but I'm having the same issue for months now with my Windows 10 64bit - Adobe Acrobat DC 21.007.20099. I can add the Quick Tools I want to the toolbar, but then after some random number of open and closings of the program, they all disappear and I have to set them up again. I've uninstalled, deleted all Adobe program files, reinstalled with the same result. No add-ins for Adobe.
