where do we log bugs for Acrobat Pro DC?

I'm long time frsutrated by the fact that if my Mac hangs or crashes, when I restart Acrobat it hasn't recorded the file paths of most recently open files. That includes files made by Acrobat itsel from say, Word files, and files simply openned in Acrobat, sometimes shared or editted, maybe saved maybe not.

Where is the bug log, please. I want this fixed its a TPITA for me. 🙂
