Google Tag manager Script still inserted when deny all

Hello Support Team,

Thanks for that great plugin.

I got a problem with the tag manager. I implement it exactly like its described here https://complianz.io/definitive-guide-to-tag-manager-and-complianz/, but even if i deny all, the script still loads. I don’t get it, how can that be?

thanks for your Help,

Best, Ralf
