I should have followed my own advice closer. Yesterday I noticed steaming services were getting blocked if you hadn't updated. There was no way to manage the services in the old app without updating. And once you updated the app it required a system update.
So in the course of trying to get SiriusXM removed and re-added I inadvertently allowed a system update to push down. And just like I warned others, the system update blocked access for the old app to control the system. And not just from the device I was using at the time - any device running the old version displays an error in the banner stating this version of the application can no longer control the system. Can't roll back system update that I'm aware of so now I'm stuck with very limited capabilites in the new app.
They just hate customers so badly they are going out of their way to force the new app on us.
