a quick question my ads that were doing good suddenly stopped spending any amount. There is nothing wrong in payments and the account is normal too. It's been more than 24+ hours. Have you faced this problem and have some suggestions? I duplicated the campaign as as I'm speaking it's been in preparing for 5hours now.

Got 6 leads in 2 days, but no leads on the 3rd day or today. Running one ad set with broad targeting at £20/day. Any tips on optimizing the ads?
