Hi,
Please use the "universal analytics" mode with "Direct Call" setting (also called Measured Protocol).
The "direct call" is useful because when the order is confirmed thanks to the IPN system (server to server) ; there is no javascript processed.
And there is no page displayed by the customer.
Because we can't be sure that the customer will ever return to the website (a huge number of customer had that problem) ; we use that "direct" call to keep a track of the order and his confirmation.
Now the "direct call" is not perfect because it won't provide the same "client ID" than the customer who made the order.
We have some patchs/improvements in progress for the plugin but we need to do more tests before being able to release them.
