We recently migrated from the Alfresco Theme to the Uptown theme. Part of the migration was to employ Google Tag Manager. Since the migration and implementation of GTM, we're only seeing about 60% of our data appearing in Google Analytics (GA). No e-commerce data is being forwarded to GA.
The question as to why we're missing transactions in GA is tough to solve as seen in this post https://gtm4wp.com/for-advanced-users/missing-google-analytics-transactions-here-are-10-reasons-why.html. So many possible reasons and so little defined testing to solve the problem of missed transactions in GA.
Are any other users of the Uptown theme having a similar problem with missing transaction data in GA?
