I have added this widget to my muse sight, filled in all of the data with consideration, I'm using a Google Spreadsheet and the KEY is correct, I have it in FIXED position mode ... but nothing shows. No hamburger anywhere. I've tried closing the site, exiting MUSE, shifting the widget to a different page ... still nothing. I'm using a Mac, Muse is v2015.2, Connect CSV is freshly downloaded ... I am completely baffled, can anyone help?
