I am typing within a note, but I notice that it will have a significant slow down when I go to erase words. Typically, I use the command shortcut to erase a whole word and begin typing again.
I am not sure if anyone else is experiencing something like this. I read a few people in the support community having similar issues a couple of years back, but it had to do with scrolling not typing. I am using a MacBook Pro 15 2018 on macOS Catalina. My Agenda app is running version 9.1.3.
