I’m experiencing the same issue. Device: Google Pixel 8a Apple Music version: 6.5, installed from Google Play After the user successfully signs in through the new Apple Music authentication UI, the activity returns RESULT_CANCELED, and authManager.handleTokenResult(data) reports USER_CANCELLED, even though the user did not cancel the flow. Logcat shows Successfully authenticated the account, followed by Failed to post account changed event with ams.error Code=1, and then DialogConnectorViewModel.cancelAction(). This flow worked correctly before the Apple Music update.
