I called support. Even they could not get the link to print my subscribed channels to work. The rep is mailing me a list. I asked him to report this problem. Not sure if it will be done.
The web link hasn't worked in the 3 plus years I've had Verizon FIOS. In general, I consider FIOS web site to be among the worst I've ever used. Even the Report A Problem Link isn't working.
Sometimes, I think I should have stayed with Cox. Will consider when my contract is up next April.
