Issues is occurring across all platforms (Android, iOS, FireTV). Provider is Verizon-FIOS. The computer hosting the DVR shows all the channels on the guide. When the guide is viewed from any other device some channels are left off or appear on my "favorites" but not when I select "all" from the guide. Then 5 minutes later when I go back to the guide the channels are not showing up on any list.
Channels I've noticed causing issues are the ESPN/ Sports channels.
I am also pulling sources from FIOS through streaming. Current setup is 2 HD Prime devices and the FIOS login for streaming. I have updated the channels listing on both HD Prime devices and restarted all devices. That did not fix the issue.
