We did an upgrade from v6.4 to v2205 as such brought along a lot of old code. We also did an upgrade from GA3 to GA4, but this is not working - we are not getting any eCommerce data.
After further reading, it seems that it is best to just throw what we have now and start again. So that is where I am at.
I have read the following: Integrating Google Analytics, but not clear to me.
I recall there was a cxworks that was posted on SAP, but it is not accessible now as SAP moves things over to the Learning area.
So, I am looking for some help as to the proper way/place to remove all the old GA3 code/js/tag and implement a nice clean GA4.
