Animation jumps on iOS/Safari

Hello Forum,
I am working on an Ionic App with angular. We are deploying our App for iOS and Android an using lottie animation in various locations. For the most part this is working fine but in some spots the animation is jumping on iOS. The example I am showing here is a robot slot machine that starts smaller and positioned in the top right corner and then, after half a second, goes to the specified position. This does not happen in chrome or on Android. Unfortunately I cannot show it as a video.

The animation is set to not loop and autoplay is also set to false. The animation only starts playing after it is being clicked. So the problem is occuring even before the animation starts playing.

Does anyone have an ideo why something like this might be happening?

Best regards
