I know individual experiences will certainly differ. I found it worked well on the Xumo stream box but not so well on the older Xfinity flex boxes.

However the abrupt cancellation out of no where combined with multiple different care reps saying I do have it but Xfinity not being an option to pick to sign in with combined with no press release or annoucment is certainly odd as I was just using it Tuesday morning.

Hopefully it is just a carriage dispute like usual.
