Thanks for all the help guys. I figured it out, and the issue is crazy dumb. So, you select your clips that you want to move together, then click and drag on one of them in order to move them all. This works perfectly fine, unless the clip you choose to click and drag on happens to be an audio clip. Then you will pull your hair out, because it WILL NOT let you reposition it/them. If the top angle in your multicam happens to be your audio clip, and so you keep trying to move by that clip (because, of course. It’s what everything is supposed to synced to!), then you’re really going to lose your mind.
Moral: Do not click and drag on audio clips to move a multiple clip selection.
I really appreciate everyone’s help trying to figure this out. This is a great community, thanks everyone!
