I accept or reject the banner, but it appears again on the next page or after I reopen the browser. Is the choice not being saved?
OptinStack stores the current choice in a first-party cookie named optinstack. If the banner immediately returns, inspect whether that cookie is written and remains available on the next page.
Common causes include testing across different hostnames, an incorrect cookie domain, blocked browser storage, an expired consent duration, calling OptinStack.renew(), or publishing a configuration change that requires a new decision. Preview and production hostnames usually belong to different registrable domains, so a choice made on one will not carry to the other.
