I bought a Vizio TV early last year and successfully connected it up to Alexa using the Vizio Smartcast skill. Fast forward about 15 months and it stopped working with Alexa, in fact the skill wasn't even under "my skills" anymore. So, I (re)enabled the Vizio smartcast skill and after I put in my login credentials (which I tested on the web) I always get the "we were unable to link Vizio SmartCast at this time, please try again later" message.
Anyone know have any ideas?
