Support is garbage. Been without Antenna TV for a week and a half after 9.4 update.
Excuse my rant, but i'm done.
TCL 65" TV here. Was watching news just fine one day around breakfast. Turned tv off, update to 9.4.0 came, and boom. No local TV at dinner. TCL blames Roku, and rightfully so. The update is the only thing to have changed.
