Source .riv/.rev file

program.riv.zip

Expected behavior

Would expect the animation to work the same way on all platforms, when using same code and same .riv file.

Device & Versions (please complete the following information)

• Device: All iOS devices including real and simulator, most recently replicated on iPhone SE (3rd generation) 17.2 simulator
• OS: iOS 17.2
• NPM Version: 10.1.0

Additional context

Other .riv files seem to work fine, but this program.riv has these animation speed issues. Our designer has attempted recreating the .riv file and modifying it several times to no avail.

This was fixed by upgrading rive-runtime on iOS to 5.7.1. Just used patch-package to do it and required at least one swift code change I'm not so sure about if it's safe.
