@dokind can you please share the error details? Any console logs? Are you using the cameraKit staging or production environment? In case of production, the snap app must be approved and live in production. Also, make sure you have also set up the platform identifiers for both iOS and Android.

[dokind]

It's working in staging but not working in prod So My app didn't deployed yet. So I have to use prod token after I deploy my app in appstore ?

[WaseemAbbas-DevCrew]

It does not require the app to be deployed on the app store but it should be approved in the Snapchat developer portal. Please read here how to set up production and staging environments. You must have a version approved in production as well.
