Did you ever figure this out? I’m having the same issue and can’t find a way to get past it.
Yes, I got the answer, just right click on the timeline where you want to add the notification and add the notify there.
Make sure you right-click in the same row as the Notifies menu at the left.
I didn’t understand how did you solve it ? I tried adding notifies but nothing appears there about notify adding…
Okay i solved it
