Lottie file lags in iphone

Hi,
I’ve noticed that the Lottie file lags only in iPhone and it starts lagging from the middle of the animation.
It has no issues when I preview it in the Lottiefiles previewer. Everything is as far as I understand built right.
What can be the problem?

Thanks in advance.

Hi @maya1
Could you check if your animation contains any unsupported features on iOS:

Hi, thank you for the answer. All the features are supported from what I see. That is why I’m so confused…

It is laggy in Lottie 4.0.1 but in Lottie 3.3.0 it plays smooth.
Anyone has a clue?

Thanks in advance.
