Remove "atid" and "atclid" codes from website urls and products

For some reason there is an “atid” and “atclid” reference appearing on our store url links and on the add to cart page under the product name. I’m assuming they were the result of a dodgy tracking app or something. How do I remove these codes, I have no idea whats causing them to appear.

I’ve figured out how to hide it from the add to cart page now, but still dont know how to hide it from the urls. thanks

no idea. i have no tracking apps installed. I do know it is a tracking parameter from my research into the issue

I think it is Any track. Its not a shopify app, its a tracking platform.

I’ve found the solution. remove the below code from the theme file
