LAST POST - I stumbled into a fix that worked for me. I deleted the paid vesion of Adobe DC, downloaded the FREE version of Adobe Reader and then after I started using the free version, it kept trying to get me to upgrade because I was signd in and it knew I had a paid version. Against my better judgment, I did upgrade. UPGRADING from the free version seems to have fixed this as I nw have full functionality. Thank you Adobe for, once again, leaving me to find my own fix (now I have to deal with this unwanted Windows 11 "upgrade")
