Google analytics script ''tracking not installed''

I currently monitor 3 websites with Google Analytics but a few days ago I started working with a brand new client and I can’t add the script into the website. I tried copy pasting it directly into the site, tried the Insert Headers and Footers plugin and the WP Google Analytics Script plugin as well. The latter I tried with both the UA Tracking ID and the actual script.

Last checked times change so I know Google looks for it but I still get the message “tracking not installed”. Also, after adding the script I checked View Source of the website and couldn’t find the code in there. https://vicole.ca

Never had this happen before, not sure if I’m doing something wrong or if I should give it a couple of days.

Any comments or feedback is appreciated.
