Using Roku Ultra (latest software on it and Tablo)
This morning I had to reboot the Tablo due to not seeing it on the network. After which, I had nothing in the “Coming Soon” of Scheduled. The shows do still show in the “All” and have the clocks in the upper right of the icon.
I am having to reselect either “All” or “New” from the “Scheduled / All” screen to have them appear in the “Coming Soon”.
Same thing happens in the Android Preview. To fix it in Android (Nvidia Shield) you need to clear the data or remove and reinstall the app. I do not have a fire stick and stopped using Roku years ago so I do not know if that will work for you guys or not.
