Current Behavior

I have an Expo app that uses Moti, however, when testing the app on an iOS simulator through Expo Snack or when running it on a device using the Expo Go app. The crash doesn't occur on Android devices or when running the app on a local iOS simulator.

I'm not 100% sure if this is a Moti issue, it could be a bug related to Expo Go, but I'm open to any solutions or hacks if you've encountered this before. Thanks!

Snack doesn’t work with moti, but expo go will.

[agrawal-rohit]

@nandorojo, is that expected behavior or an incompatibility issue with Snack and Moti? Also, when you say that Expo Go will work, do you mean only during development?

[nandorojo]

Moti works fine. But expo’s online snack editor has issues with libraries that use reanimated, which is why moti doesn’t work there.

it works fine in any actual app that isn’t on snack online

Hi @nandorojo , the installation mentioned Please follow Reanimated's installation instructions for v2. for Expo. Does reanimated v3 works? I'm running into this production only issue: #334

[nandorojo]

Yeah, though you should upgrade moti on that example

Yeah, though you should upgrade moti on that example

Hey @nandorojo which example are you referring to? If you are referring to my demo in the issue I raised, isn't 0.27.2 already the latest moti version?

334 is fixed by upgrading react-native-reanimated.
