When you related a banner to a Cart promo, does that mean that this banner will only show up if the rule is applied or it will show up if the rule is active.
Let say I do a cart rule that give 10% off on order over 100$. I link a banner to that rule but the banner show up even when my cart is under 100$.
Is that the expected behavior ?
No, it should show up only when that rule is applied.
Share screenshots of configured rule / or configuration in order to be able to spot the issue.
