It is not SDK 46 problem! @brentvatne @da45

With SDK 45, Expo Go 2.25.1 grey block on android, crash on ios. With SDK 46, Expo GO 2.25.1 grey block on android, crash on ios.

But, With SDK 45, Expo Go 2.24.3 work.

How to downgrade Expo 45 with Expo Go 2.24.3.

- Delete Expo Go app from Simulator and Real Device.
1. expo upgrade 45
 - Downgrade to sdk 45, because  Expo Go 2.24.3  doesn't support Expo SDK 46.
3. expo start
  - Expo , automatically install expo go 2.24.3.

Now you can wait for fix Expo Go problem 😃

you can create a development build of your app with your own api key, without needing to use ‘bare workflow’: https://docs.expo.dev/development/introduction/
