This animation renders and animates properly when I test it locally. If you are seeing something different, please share a sample project that demonstrates the problem and reopen this issue. Thanks!

It's possible this is a bug that was fixed in a recent version of Lottie, since 4.3.1 is not the most up-to-date version.

Thanks for the reply.

I see what you mean, but this animation doesn't render and doesn't animate on the iOS platform. Is it possible that the issue persists on iOS platforms?

I am testing with the lottie-ios CocoaPods installation version 4.3.3 in my own project, and I can't see it working. I can run other JSON files properly, but not this one.

The version 4.3.1 is returned by the LottieFiles current app downloaded from the App Store.

Thanks!

Perhaps this was an issue fixed on master but not fixed in 4.3.3. We released 4.3.4 yesterday, maybe give that a try.

Yes, it works properly in 4.3.4. Thank you so much!
