# Will Facebook ads go to the learning phase again if I update my existing ads' UTM template?

According to the [Significant edits and learning phase](https://www.facebook.com/business/help/316478108955072?id=561906377587030), UTM template update is not considered to be significant edits. You may have several minutes up to 1 hour ads pause since Facebook will review your ads update.

We also get very few cases that the UTM update will lead to a learning phase. If you get the message from Facebook, please contact Facebook support team for clarification.
