Denied cookies are still set after the page refresh

Hi guys,

whenever I land on a page first time and accept the stricty necessary cookies, the other ones (like “_ga” or “_gid”) get deleted immediately as expected.

However if I refresh the page, the cookies are set again, and the consent preferences are not taken into account. What could be the reason behind it?

Our GA implementation is via the Google Tag Manager, if that matters.

Thanks
