Alexa App not showing tv

[Mars1954]

I use to see my LG TV in my alexa app settings and now its gone how do I get it back I use to be able to hit my home button on my Alexa remote and my TV and receiver would come on at the same time I have my fire stick in a HDMI port on my AV receiver and then it goes to an Arc enabled HDMI on the TV

try deleting the lg skill in the alexa app and then enable it.
