Edited an ad set and it dropped back to 'Learning'? Checklist before you panic.

Edited an ad set and it dropped back to 'Learning'? Checklist before you panic.

Learning phase = the ~50-conversion window Meta uses to calibrate. Resetting it costs money.

What actually resets it:
— Budget change over ~20%
— Swapping the offer/optimization event
— Pausing 7+ hours then turning back on
— Editing creative inside the ad set

What does NOT reset it:
— Budget bumps under 20%
— Name changes
— Turning OFF an ad inside a set with other live ads

So before you touch anything: ask 'does this nuke my 50?' If yes, dupe instead of edit.

Keep a sticky note with these 4 reset triggers next to your monitor. Saved me three relearns last week.
