I found a topic related to my issue: https://theme.co/apex/forum/t/google-tag-manage-and-google-analytics/8966/6. I have followed all of the steps to edit line 30 to make it work, however the website (allamericancleaningservices.us) showed the correct code but did not show any live traffic even though I was on the site through 3 different devices.
I then found a Google Developers blog post to use the old UA tagging code and that is what is live now. Still no live traffic on the site but the code is present.
What could be wrong?
