Lottie with base64-encoded data

## 💬 Questions and Help
Hi,
I have this working with most of Lottie files that consist of vector data but when I try with a lottie file that consist of base64-encoded data it wont run the animation, just showing the first frame. Something I can set to make it run?

Best Regards

No source files, tests, or entry points are named. Start by reproducing the issue with a base64-encoded Lottie asset and compare it with a vector-only animation; done means the encoded animation plays beyond its first frame on the relevant Xamarin platform.
