Radial gradient works in preview but not on android + iOS

I’m using a simple ‘radial gradient’ onto a shape layer in After Effects. When exported through Lottie or Bodymovin, the file works perfectly in Lottie preview but developers on Android and iOS report that when they input into the app it’s showing as static.

Does anyone know why this is happened?

Can you share any screenshots? It’s a supported feature so I wonder why it’s not moving.
