SiriusXM app and SiriusXM website not working

I hadn’t used the app in awhile but today needed to do that and all I get is a blank screen. Couldn’t reach the website cuz safari said it was not secure and wouldn’t let it open. I deleted the app and went to reinstall and my iPhone now won’t even allow the app to be installed. 🫤 So no way to update the app. And I have restarted my phone twice!
