August 2021. Same issue. Windows 10 is up to date. Just trying to install the Spectrum TV app. It's shown as purchased in the Microsoft Store. In my Microsoft Account, my PC is shown as the only device, and that is the device upon which I am trying to install this app.
WSReset opens up the Microsoft Store, and I see Spectrum TV in my library, but it gives me the same error.
Just ludicrous. I started screaming a little while ago, so it's probably time to walk away. :D
Has Microsoft spent any time trying to fix this issue? If you purchase an app and this error happens, do people get refunded?
Thanks!
