Comcast and Fire TV

I have read through most of the issues with Fire TV and Comcast.  I have added Xfinity info to one TV but not the other.  I reviewed my bank statements and see charges for the use of the app, which I suspect is because of access to it on the other TV.  It has been cancelled as of today but I am going to look again.  Is anyone having this specific issue?  It's ridiculous to have archaic incompatibility.  It is for this very reason people get rid of cable and only stream television.  I am being charged for sports channels that offer nothing because of COVID and no sports.  Almost $300 when I had signed a contract for two years for under $200.  Comcast/Xfinity is insanely priced and with all the streaming happening now and people staying home more, why pay for cable?  If it's costing me extra money because of the Fire TV, and I have two of them, I'd rather stream.  C'mon, Comcast, do something for the people.  The monopoly on services is absolutely inhuman.
