<b>Edited an ad set and tanked it? You reset learning.</b>

Learning phase needs ~50 conversions in 7 days. Touch the wrong field and the counter goes back to zero — CPMs spike, delivery stutters.

What actually resets it:

— Budget change over ~20% up or down
— New creative, audience edit, optimization event swap, bid/cost cap change
— Pausing 7+ days

What does NOT reset it:

— Budget moves under 20%
— Ad name, ad set name, schedule end-date tweaks

So scale spend in 15-20% steps, wait 24h, repeat. Slow ramp keeps you OUT of re-learning. Try the stair-step on one ad set tonight.
