Since this latest update has happened, my channels are really slow to come on. I thought maybe it was just one or two channels but it’s happening with all of them. When I click on the channel and want in the guide it spins forever before the channel comes on. It was working great until the update.
This happens on all devices? Even your phone?
Not sure if this will work or not, but try a short press of the reset button on the bottom of the Tablo. I have had the slow channel problem in the past, and the reset worked for me.
MIne were loading very slowly on my Televes/Tablo4G/Firestick but rebooting everything (including the antenna) fixed it.
I did a reboot and it seemed to help for now.
