Animated Prototyp with countdown does not work when shared

Hey

I am working on a animated Prototyp with a countdown effect. So if the users clicks on the product the coundown starts (60 seconds). Because the timer should work on the background if the user goes back to all products I have done a lot of copies to do a work around for it. If I test my prototyp ind XD everything works like it should. But if i generate a link for sharing it stocks on the first screen with a loading circle.

Screen one shows the first page of my prototyp. I have 2 products, one with a timer and one without timer. If I click on the silver watch it should start imidiatly with the countdown, but it shows the second screen. 

If I click back and again on the silver watch it works like it should....

Link to the prototyp:
