Hi There @johnhansen033
I certainly understand your frustration here. With regard to our Google Analytics extension, it is not compatible with Google Tag Manager code which comes with Google Analytics code. So we do not recommend to use it for now.
With regard to Analytics Code placement, you can either integrate into your header or footer area. It's totally depending on your site specific details such as, what are the other priority scripts that you want to load on your header and whether you want to increase site loading speeds etc. To get an idea, you read more information here.
With regard to above provided link (Kinsta Reference), you can see there are two methods that you can use to integrate Google Analytics. The first method is using the plugin called Header and Footer. If you want to implement the manual method, you need to utilize the function which you can add into your child theme's functions.php file.
Basically you can name
your_function_name as any name that you would like, however it should be a unique name. So for example
If you have further confusions, you can see an example from here.
Hope that helps.
