I have an LG smart TV with the now app. I bought the now TV package through amazon as they had an offer. I cannot log in on my TV as it's asking for my username and password. I have tried using my amazon login but that doesn't work! Help please!!
Go onto the app on the fire stick. Scroll all the way to the bottom until you see a row of options, one should be “account” in there you’ll see the email/username that’s been logged in on the app.
Then you’ll be able to use those login details for any other supported device.
