Anyone have Youtube Ad experience with campaigns not delivering and could lend a helping hand? I've got a campaign that's been running for 4 weeks at a 600% CROAS, Target CPA objective, it's slowly been declining in reach/ad spend, hitting £100 to £200 a day lately but yesterday it just stopped delivering. I have another campaign targeting the same audience but in a different location that also just stopped delivering yesterday too. I have other campaigns running fine with same settings to a different audience in the account too. Does anyone have any ideas what could/could of caused the sudden stop in delivery for this audience? Or what I could do to get it delivering again? Thanks for your help guys
