I went ahead and logged into  https://mspamystic.com and added GTM and GA code to site.
Isaac
for some reason, I am only able to see the GTM and GA codes on the ABOUT US page.
Not sure why that is. 
Can you please let me know what I did wrong? 
Thanks,

Hector - You had them placed in the wrong locations. Also, I would recommend adding the analytics code directly in the child theme of the website instead of in the theme panel as after some time when the theme gets out of date most of the time the first thing that gets stops working is the theme options/panel. 

I have now moved them from there. Please check again now on your end.

Can you please send me a screenshot to what locations you added them? This way, I can do them once in a while and free you up for more important things. 
Anything that is too complicated, I leave to you anyway. Thanks. 

I see it working fine now, thank you Isaac. 

Hector - I added them directly in the theme PHP files via SFTP.

Okay, that sounds a bit more complicated than I expected. Adding the code directly is easier for me. But this I will leave to you. 
Thanks.
