I found out that since I have Spectrum Silver I also have access to HBO Max. So at first I was looking through my cable channel lineup to see which digital channel it was on. I don't know how long it took me to realize that HBO Max is a streaming service and not a cable channel.

Managed to sign up for it around late December 2021, managed to see Wonder Woman 1984 and Singing in the Rain as well as binge watching the West Wing, the 2020 Perry Mason series and currently going thru Doctor Who.
