I have an RCA roku tv. i am not able to open developer setting using home home home up up right left right left right sequence. I was able to do it few days back and not anymore. I installed one of the app and it just disappeared yesterday when I turned my TV on. Also, I am not able to open my tv IP address on my laptop. It just hoes into error.
Any help regarding opening IP on laptop or other way to open developer setting is appreciated.
