Program monitor will not show footage
We've run into a very strange problem that we've only encountered in CC 2019. Any projects created natively on our machines playback footage just fine. We can scrub the clips in the Source monitor, and they playback great in the Program monitor.
Where we are seeing a bizarre issue is anytime we go to open up the project on someone elses machine, we can see the footage play back in the Bin and Source monitor, but can not see the footage in our sequence in the Program monitor. It happens inversely on everyones machines. E.g. original project created on machine A, loaded up on B, won't play back. And likewise on machine B, trying to view on A, doesn't show up..
Attached is a screen shot of what we see.
Clearing caches, quitting, restarting, etc with no luck.
