What happened to DRAW FREEHAND in Acrobat DC?

[Darque Hellmutt]

1.  Been using Acrobat for YEARS, and was finally forced into this version.
2.  Have been using DRAW FREEHAND to flawessly add notes - even full sentences - to documents for YEARS, up until this week (about 28oct24).
3. Out of nowhere. I write ONE (count 'em! ONE!) character, and the program drops out FREEHAND and defaults back to SELECT.  
4. Have I inadvertently flipped a switch somewhere, or did a coder hickup during an update?
5.  FWIW, my HIGHLIGHTER is now acting like the DRAW FREEHAND tool.

Any insights or suggestions would be greatly appreciated.
