I’m doing everything but I’m not using cloudflare, I’m using cpanel. So I stucked somewhere. I can’t use powerups. Where is my fault I can’t understand because of stape’s videos indicating cloudflare and mine is cpanel.
Regardless of where you manage your DNS records - the point is the same, you need to add the right DNS records for the subdomain to be used for your sGTM container.
If you’re not sure how to do this you should ask your developers, they will definitely be able to help with this.
