I’ve been having this issue while using the menu TV guide on my Tablo dual HDMI.
Using the menu guide, it will always show the data for approximately 2-3 seconds, re-loads the guide, and then shows the guide again for 2-3 seconds. It’ll continue this cycle until either I stop scrolling through channels or after I already pick the channel.
However, using the guide while already watching a live channel (by hitting the up arrow on the remote) will not have this issue.
It’s very strange and also frustrating for me. It wasn’t an issue when I first bought it in December 2021, but now it does it every time I use Tablo. I’ve tried clearing my user interface data, and resetting the device multiple times. It hasn’t fixed it I need help please.
