Hello! I have Toshiba Fire TV Edition and Amazon Echo. It is linked to Alexa App on My Cell Phone. Everything was working just fine until one day when something Changed and I do not understand what? One day I've asked Alexa to switch Input on my Fire TV and I've got an answer: "To use your Fire TV device Re-enable it in a smart home section of the Alexa app on your mobile device".
I really do not understand what I need to do? Can somebody help me to understand how can I do what I've asked? if this is possible, step-by-step would be nice.
