The app on LG TV is terrible and freezes, blue screen and not communicating with the server. Please fix!!
I also have a LG TV with the TABLO app installed. And an Android phone with the Tablo app installed. My experience is that if there is a Tablo issue, the app on my phone will mirror the issue you see on your LG TV. I’ve only had my Tablo for about 6 weeks, but in that time I’ve found that the near constant issues I’ve had were primarily two things: technical issues at Tablo’s end, and antenna issues at my end. Antenna placement and whether it is ideal for reception of the various frequencies transmitted by your local stations, as well as the distance from their OTA towers can cause problems. I set my Tablo up via Ethernet cable to my router. I tried and failed to make a wifi connection to my router. Current remaining issues for me remain having a proper antenna for reception of Lo-VHF band transmitter signals from the local ABC affiliate. I think the issue you have has nothing to do with Tablo’s LG TV app, and everything to do with the points made above, at least in my experience.
