After installing app to androidtv and launching the app .He will ask me to log in to www.zoho.com/tv and enter the code that the app will display on your TV screen. Log in using a computer and enter the code, then a message indicating that the device is accepted. But on tv screen still app shows code and countdown of seconds. When this countdown ends, it simply gives a new code and the countdown starts again.

What would help?

TV restart did not help.
