Learning Limited Facebook ads

Hi Guys,

I have one question,i was testing my product with 8 ad sets with $5 each and I got a few sales first day and second and then all my ad sets went to Learning Limited, and immediately CPC went up and CTR went down and got 0 sales on the third and fourth day.

Then I tried 4 ad sets with $10 each and the same thing, first 2 days went great, got sales and good traffic, and then after 3rd day all went down and got Learning Limited.

Is there anything that i can do so i can be longer in Learning Phase and eventually in Active because i can't do anything when after 2 days my adsets go to Learning Limited,i can't wait 2 or 3 more days and then scale winning adsets.

Thanks in advance 🙂
