Alex has an Samsung Note 8 mobile device, and after an operating system update, he's lost the abilty to stream music. Leo says that some updates will cause some apps to stop working, and if you used an app that is no longer supported, like the Milk streaming service, then you will lose the ability to use that app. Leo also says that Verizon often doesn't give updates in a timely manner. So it's not surprising. But you may also want to check to be sure that your app is still supported or updated. Or try another app.
