Flash (the deprecated plugin Spectrum use to show TV through a browser) is deprecated and will be disabled in all browsers in 2020.
Can Spectrum please confirm they have a migration strategy, and also dates for this timeline?
Thanks for posting. There is currently no time line available. Any updates or changes will be announced prior to being launched. You can find information about Spectrum TV at https://www.spectrum.net/support/tv/spectrumtvcom-support/
