Missing clock issue seems to be resolved. Thank you.
One note: When clock was missing I could still stream content, but the Alexa ROKU skill would not work. It was unable to communicate, even though internet was available for streaming. If I restarted the TCL TV and the clock was present then Alexa ROKU skill would work again until the next time the TV was off and a power ON would not show the clock. Just a note to provide to the developers about some of the behavior.
