Cookies do not fire in GTM preview mode when scrolling

  • Hi Andrea,

    This issue with GTM could be caused by several things such as unclassified cookies or browser problems etc. 
    Could you first check if all cookies have been classified, because this could be caused by an unclassified cookie being removed.
    If this is not the issue I would also suggest you to check in a different browser. If changing browser does not work it could be because GTM Preview hijacks the scroll event in a way that it cannot be used.
    Other possible suggestion about this issue would be that it can be caused by css, if scrolling is stopped by overflow settings.

    If the problem is still there checking the above mentioned suggestions, you could send us the domain so we can test and investigate further more. You could send us the domain in question at
