Notifications: FIS_AUTH_ERROR after upgrading to SDK 43

Please provide the following:

  1. SDK Version: 42/43
  2. Platforms(Android/iOS/web/all): Android

My SDK 42 packages:

    "expo": "~42.0.1",
    "expo-notifications": "~0.12.3",
    "react-native": "https://github.com/expo/react-native/archive/sdk-42.0.0.tar.gz",

I recently tried upgrading from SDK 42 to SDK 43. I rebuilt my development client and I seem to be getting this error:

[expo-notifications] Error encountered while updating server registration with the latest device push token. Error: Fetching the token failed: FIS_AUTH_ERROR

Nothing else changed in my project. I then git reverted back to SDK 42 and rebuilt my dev client for SDK 42, but I’m still running into the same error.

I’m wondering if my server config is borked on the Expo side, similar to this post Fetching the token Failed, message : FIS_AUTH_ERROR?
