Hi,
But since when ?
Does the google analytics plugin was enable all the time ?
Are you sure that the time schedule is the exact same ?
Can you see specific orders on specific days which are not included in Google Analytics ?
Which mode of the plugin are you using ?
If you do not use "universal analytics" mode ; the plugin can't use the measure protocol and the order MUST be validated by the customer returning in your website.
