Same Issue. Roku Ultra has the live guide while the TCL TV does not have. Both are on the updated 9.3 firmware. The TCL Roku TV firmware was a forced by update by asking it to connect to the wireless speakers otherwise it was stuck on 9.2. It seems that the Roku TV's are not getting the updated Roku Channel app. It might be a licensing thing with the TV manufacturer as some ppl might confuse it with the OTA / Antenna guide
Same issue. It’s only the TCL Roku TV that is missing the Roku Channel Live TV Guide after upgrading to 9.3. Both of my Streaming Stick+ 4K’s have the Live Guide after getting the 9.3 upgrade. Strange.
