Due to the limited usage of 2G network, we expect the current 2G Google intervention to a minimal impact on enterprise customers at this time. We are proactively addressing future issues that may develop if Google continues to promote practices that contradict Internet community standards.
DTM’s goal has always been to create and support the most powerful and flexible features in the space. We believe that must include allowing our users to leverage both synchronous and asynchronous technologies.
Customers who are significantly concerned about 2G Chrome users can use a more asynchronous deployment of DTM and continue to use the robust set of asynchronous specific features of DTM.
If you are seeing this warning and want to use DTM with a more asynchronous deployment, and remove all “document.write” calls (and remove the warning), please do the following.
3rd Party Tag
If you are deploying 3rd party tags or JavaScript via rules in DTM, and are concerned about visitors on a 2G cellular network who are using Chrome, please do the following:
- Review all 3rd scripts that are deployed via “Sequential Javascript” or “Sequential HTML” for “top of page” or “bottom of page” positioning rules.
- In the code editor, change the Type to “Non-Sequential Javascript” or “Non-Sequential HTML”. Note: any functionality that requires synchronicity will no longer work.
- Review the code within the editors to ensure it isn’t using “document.write". If the code you are deploying through DTM uses “document.write” it may be affected.
- Test well before deploying.
