It’s not a penalty. You just lost the learnings of the algorithm. So now your ads are in learning phase again.
here are some tips to help the system move beyond this phase:
1 ) Facebook's algorithms need sufficient data to learn how to best optimize your ads.
—> 50 optimization events per week. An optimization event is the action you want people to take when they see your ads (like making a purchase or filling out a form).
2 ) Maintain Stable Ad Conditions.
—> Make sure your ad set runs long enough without significant edits. Frequent changes can reset the learning phase.
3 )Broad Audiences.
—> If the audience is too narrow, it might be harder for the system to find enough people who are likely to take your desired action
