I am migrating from Tag Manager 1.0 to DTM. I copied my legacy s_code with all the customizations from last 4 years and pasted it in DTM Code editor.
Note: I removed the Appmeasurement library and made the code editior blank in DTM and then pasted the compressed legacy s_code.
When I switched ON the DTM stage cookie. I am seeing 2 image request. One from DTM and other from legacy code with the same variables firing. My goal is to fire only 1 image request. Your response is appreciated.
DTM fires the s.t() call by default when you use the Analytics tool. So check to make sure you are not still firing the s.t() call separately within the page code. There are definitely use cases where you would suppress that default s.t() call within the Analytics Tool, such as for an Angular application; but for most cases it's easiest and best to rely on that call instead of a "hard coded" s.t() call.
