i bought one fire stick and loved it. A few days later I bought a second one . I got the second one working, turned the tv off . I tried to use the tab that has my first fire stick and it doesn’t work. The second tv doesn’t work either with its fire stick. I turn my router off and on and turned my wireless printer off. No luck. The message is “no signal” when I put the proper input on the tv for the fire stick. Am I doing something wrong?
