Keeps asking me to sign-in to Adobe on Mac

How to stop Adobe Acrobat DC repeated sign-in requests on mac. I tried searching on Adobe site, and one place it talked about folder permissions, and mine were already exactly as they said. Other places it pertains to WINDOWS. Anyone else know how to stop this asking me to sign-in every time I open a PDF file?

...or is there another app that works well and is MADE FOR Macs to open PDF files?
