Google-site-verification shown on every page - help

Greetings everyone!
Could some one give me a hand here? While implementing GTA code this bad boy showed up (see the image below, bottom left corner) on every single page and I just can’t remove it. Is it an issue on my end and Webflow, or do my clients need to do something with Google and their site verification? Thanks in advance!


Here is my site Read-Only: Webflow - KLD

With Webflow you could use a meta tag in the head or a DNS method to verify your property if you are not already running GA. See Verify your site ownership - Search Console Help and follow the instructions.
