Bug: AE mogrt with responsive design time does not work as expected in PPro.
I am using AE 17.1.1, and PPro 14.3.0 build 38, Windows 10 Pro version 10.0.18362 buld 18362. I created a mogrt in AE with a protected area on the beginning and ending of the mogrt. In Premiere Pro, when I used the selection tool, the mogrt would not lengthen,and if shortened, the ending protected area is chopped off. Note that the "reset duration" item on the "graphics" menu is greyed out.
Thanks to great information from users, we were able to nab what appeared to be the true root of the issue, a problem with the timing getting wiped from the project if no explicit interaction had been made with the timeline (like muting or unmuting a track).
If you head over to the Creative Cloud Desktop App and navigate to the Beta Apps section, you can download the Beta version of Premiere Pro (any version after 14.6 × 46) and the fix should be in!
Please let me know if the issues still occur for you, though. We want to put this one away for good, and are hopeful this time. Those zombie bugs are wild though!
The Reset Duration option is still available if needed as well.
