title: Discrepancy between google analytics transactions and Odoo number of orders
body: <p>I have added google analytics tag to my client's website (They are using Odoo platform) through a Google Tag Manager Container. I also (Along with their backend developers) implemented the data layer to activate the enhanced e-commerce feature. it used to work perfectly, however, about 2 months ago we started to see a discrepancy between GA transactions and Odoo Sales orders. In March, GA reported 35 transactions, while Odoo reported 128 for the same time period (from 1-3-2021 to 21-3-2021).</p>
