Hi. On January 23, I installed your update for version 3.6. I noticed my writing pen stopped working. Just now, January 25, I installed your update for version 3.6.2, but nothing has changed. The situation is the same with the highlighter pen. When I try to make an annotation I cannot see anything, it doesn’t matter color, width or mode.
I uninstalled and tried again, to not avail.
My OS is 10.13.6 and I am on a MBA 2011
¿How can I go about this? thank you in advance.
