Showtime w/paramount plus-no streaming option?

I too am very frustrated with Showtime and Paramount+ Streaming.
I have TiVos and my own Router.
Showtime discontinued the Showtime Anywhere App and replaced it with the Paramount+ App.

My Bill and Account say I have "Paramount+ with SHOWTIME", however the Cox website seems to indicate that the only way to get Streaming is with a Rented Contour Box and a Panoramic WiFi Modem/Router.

I want my Free Streaming Without renting any additional equipment from Cox.

Cox, Please fix this and allow customers access to Streaming with any compatible device, i.e. Amazon Fire TV, Roku, etc.
