Looping Overlay Not Working on App

I wanted the overlay to move quickly. It won’t preview on the app but on my computer everything looks perfect but when I go to the app the overlay scene won’t move, and some other things won’t work, I have to fast forward and then the overlay moves. My main concern is why it won’t start when I transition to the next scene.

this whole scene doesn’t work, I was wondering if it’s my app problem or not so if you guys want to check I can send you the link to my story which episode 8 is the testing episode that it’s on, maybe it works on yours
