I restarted the app, which seems to have fixed the issue. Sorry, I didn't see the posts below which said the same thing. Thanks!
Same here on an iOS Mac. I will try a restart and see if it works
I have the same issue. I'm on Mac Catalina with AT v2.3.16. I've closed AT and restarted my laptop (multiple times) and the issue remains. I open Display Settings from the Display icon and try to add fields into the "Display contents from expanded events" choices. I can't grab them to drag. I've tried various combinations of keys (Shift + Command, Command and the mouse, Option + Command, Control + Command) and nothing is working. I can remove items but then can't add them back.
Hi, Sorry to hear you are still having these problems even after you close and reopen the timeline file and restart the application. Are you able to open one of our example timelines and see if you have the same issue on these files? Jess
