acquireToken, acquireTokenSilent, and getAccount may return Promise<undefined>. This matches what the underlying native libraries return.
The Android msal_config.json file that was previously required is no longer needed and is ignored. You can safely delete this file. All options are now configurable in the config object which is passed to the PublicClientApplication constructor
The PublicClientApplication constructor no longer takes a second init boolean argument, and initialization must be done manually by calling the init method:
```
-const pca = new PublicClientApplication(config, false)
+const pca = new PublicClientApplication(config) // No longer initializes client. You must do this manually 👇
try {
  await pca.init();
} catch (error) {
  console.log("problem in configuration/setup:", error)
}
```

A new maven repository is required to be added to your project build.gradle (if you are using Expo this is done automatically for you):

allProjects {
  repositories {
    // ...
    maven {
      url "https://pkgs.dev.azure.com/MicrosoftDeviceSDK/DuoSDK-Public/_packaging/Duo-SDK-Feed/maven/v1"
    }
  }
}
