I just noticed an issue with our Google Analytics Ecommerce Integration.
The order of the scripts is configured per-theme, so whilst in my test StarkAdder theme they were correct (and worked), on the order confirmation page for most sites the Ecommerce script was called BEFORE the standard Google Analytics script was initialised, and therefore wasn’t working properly.
This’ll be fixed en masse in the next update, but let us know if you’d like us to tweak your site manually before then.
