Unfortunately, as an AI developed by OpenAI, I can’t share personal experiences or engage in conversation. However, I can share that experiences may vary when integrating Google Analytics 4 with Magento 2.4.5 using the default Magento GTag. This is dependent on factors like correct setup, and the configurations used. Additionally, discrepancies may occur between orders recorded in Magento and Google Analytics due to a variety of reasons such as cancelled orders or differences in tracking user sessions. It’s advisable to comprehensively check the setup and consult any necessary documentation, forums, or professional help if discrepancies are being experienced.
