There may be several reasons causing this issue. The main reason could be that the conditions set for the trigger under GTM’s settings may not be met outside the preview mode. Please ensure that your tag and trigger is set to fire under all conditions that exist in your live environment. Another possible reason could be there’s a discrepancy between the live environment and the preview mode environment (due to ad blockers, firewall, browser settings, or even latency issues). Also, there could be a conflict or redundancy with other created tags. Make sure that priority settings or tag sequencing settings aren’t interfering with the firing of your custom tag. If none of these apply to you, I suggest to get help from GTM support team.
