i have the same issue , i added the id to the woocommerce tab but its hard to believe it can track it with just the code. since Google provides the id and the script i added both. but my theme dident have a place to add it and i didnt want to try to figure out how to add it threw the editor or i installed a plugin called “insert headers and footers” i pasted the code there but my Google analytic is still saying no tracking info. im going to wait 24 hour and see if it updates but i would like to know i have it done right . if i dont need it in both places i would like to remove it so its not interfering. also what about the ad words conversion code?
