I'll just say that the software is poorly designed and buggy. They really need to design a new timeline system because after you have all of your assets in place, it takes FOREVER to set-up proper timing and animations.
I honestly could have done this in After Effects in half the time.
Just venting because it's 4:30 PM and I want to go home, but still got 3 hours to tinker with this bullshit.
I'm sorry to hear that you are having a frustrating experience. If there is anything in particular I can help you with regarding adjusting timings (or anything else) please let me know.
