Hi all. Sorry for the two posts in one day. I have noticed that if a device size changed trigger loads with a page it runs fine and will continue to trigger on every device size change. If you enable the trigger during a page (via another trigger), or in some occasions when content is being revisited, the trigger doesn’t appear to run. Is there a reason/work around for this? ---

Just to clarify this further: - When this trigger runs at page load it checks the device size and runs the trigger appropriately. - When the trigger is enabled after page load, it does not check the device size until there is a change. ---

Hi @Mitch - it’s a bit hard to diagnose remotely. If you dm a link to your course in the editor I can take a look - thanks-Sam
