The advertising works well and makes the profit.
And then metrics begin to deteriorate for several days, although there were no changes in advertising campaigns.
How to come back to good indexes?

Is very important for a specialist to supervise not only the performance of ads but keep an eye on listing in general.
So we analyzed the niche and the recent changes in the campaign manager and found no reasons that might've influenced the deterioration of metrics.
Also, seasonality couldn't be the reason, because the niche is in the middle of the high sales season. The only one parameter that has changed - the rating, which fell by 0.2 points.
ACoS increased from 33% to 55%, while the conversion rate decreased.
We analyzed the listing and noticed a new negative review.
Immediately contacted the buyer, and we were fortunate to agree that he would remove the review.

Sometimes the product manager is coping with these kinds of issues, but sometimes it can be missed by the product manager as well.

So keep an eye on listing in general!
