Animation stopped working on Android #383

🔙 Regression

We had animations loading on Android and iOS, and somehow (maybe with Android 12? Not sure!) They stopped working on Android, but still work on iOS.

Old (and correct) behavior

Displaying the animation on both platforms

Current behavior

Crashing on Android
