Getting message: "Unfortunately, we cannot support high speed data customers without a video subscription." (Error: createDrmSession, -1) on Roku 3.
Instant TV works on phone. And yes, I do have TV and internet service from Comcast.
I found another thread that addresses this but can't find a way to "reply" to the thread or PM the Comcast employee as instructed in that thread. Thread was active last month and not marked "solved". This is rediculous!
Sorry for the experience you're having. I've received and replied to your private message after doing some troubleshooting. Has there been any changes on your end?
I hope all is well. I haven't been able to confirm whether or not your issue has been resolved. If you are still in need of assistance, please send me a private message and I'll continue to investigate.
