No matter what advanced variables I use with $(twitch username) they always return the basic query response:
Night is currently live playing Super Mario Kart at 720p, 60 fps with 64 viewers since Mon Dec 07 2015 22:10:56 GMT-0500 (EST) (4 hours, 3 minutes, 50 seconds) - http://www.twitch.tv/night
I have a strong suspicion the text formatting on your phone is messing up the commands. You should be inputting straight double quotation marks, not curly ones.
