Description

Summary:
Upon switching accounts in the iPhone "Music" app, the "Cancel" button does nothing and the app must be force-quit

Steps to Reproduce:
0. Have multiple valid iTunes accounts (I have accounts on multiple international stores, and used USA and Canada for this test)

1. Open Music app
2. Tap "person" icon at upper left
3. Tap "Sign Out"
4. Enter credentials for other iTunes account
5. Acknowledge alert that "You will be switched to the [Country] store"

Expected Results:
Can click "cancel" and return to normal Music app activities, with your purchases from that store streamable
