Xfinity app - "Sorry, Something Went Wrong"

Running the latest version of this app, Overview and Security seem to be OK, but if I open Connect or People, I just get "Sorry, something went wrong".  I've cleared the data, I've un/reinstalled the app, I've gone off wifi, same thing. Just "Something went wrong" every time.

This is kinda not a good thing if you're forcing people to use this. I'm only using an xFi gateway for the cheaper unlimited data, but I'm starting to regret that decision.
