Hi! Theme testing isn't showing up in Google Analytics. Looking through the support threads, it looks like the plugin hasn't been updated to work with Universal Analytics yet and that might be the problem? Or has that update gone through?
For reference: According to Google, Universal Analytics is now the standard code base for Google Analytics, and all Google Analytics properties have been transferred to Universal Analytics as of May 2016. (https://developers.google.com/analytics/devguides/collection/upgrade/)
