  1. I have a Gen 1 Firestick, error message ‘Invalid Server URL’ when trying to log into Sportztv. I’ve tried everything listed accept the login with PC and Firestick. Any suggestions?

  2. I have a current Firestick 4K with Alexa ( 2nd Gen ) bought direct from Amazon prime. It is used on a non-smart TV from LG with a single HDMI. It works absolutely fine with all of the standard Firestick apps. However, I wanted to download Now TV and have successfully downloaded the app using URLs …2WgAat7 and …2S37F2N. Both failed to properly display Now TV although they loaded. A message was displayed to the effect that the app was incompatible with the TV ( ie Firestick ). The latter URL was posted on the internet as the app source as late as mid-Feb 2020 so I am at a loss as to why it will not properly execute on my setup.

    Any thoughts?

  3. Je voudrais juste remercier beaucoup l’auteur de cet article, qui m’a permis, grâce a des explications simples et précises, même pour un français, de retirer ce message d’alerte qui polluait tous mes téléchargements
    Merci beaucoup de passer du temps pour éclairer les béotiens .
