Hi,
Sorry for the late answer.
I performed some new tests and with the modifications from the post #181833 ; I have some elements in my Google Analytics report.
I also made some tests using the paypal notification and I needed to make another modification in the plugin to make it work.
You have to replace
'cu' => $account->currency
By
'cu' => $currencyInfo->currency_code
twice in the plugin.
The data is right received by Google Analytics (regarding the "real-time" overview) and I also get the data in the "Conversions > Ecommerce" dashboard.
Please let me know if you have still issues using the two modifications.
Regards,
