A community member imported a cookie banner in their project settings, but it disappears after one millisecond. Other community members suggest this is a common issue with imported cookie banner code, even from GPT. They recommend sharing the project link and published site for help. One community member provides a link to the project, and another suggests the cookie banner code should be in an HTML embed with "client only" enabled, rather than in the project settings. The community members seem to have found a solution, with one expressing gratitude for the help after struggling for hours.
