I started seeing 2 warnings repeat when starting the player today. I’m currently using "@amzn/react-native-kepler": "~2.0.0", and looking trough the documentation I for KeplerAppState and useComponentInstance I seem to be following the documented pattern. Also when searching the module I don’t see…

Hello @will.harris , Yes, useComponentInstance has been discontinued and recommendation is to use getComponentInstance. Please see the documentation here . Thanks, Rohit

Seeing the same issue, here, trying to implement useKeplerAppStateManager using the documentation, and even the exact comprehensive example app from the documentation, and getting ‘“@amznamzn/react-native-kepler”’ has no exported member named ‘useKeplerAppStateManager’ with "@amzn/react-native…
