The problem I have is that once I launch an ad campaign, the first few days the campaign works very well and I get a lot of leads. After those first good days, suddenly I don't get any more contacts (not a single one, as if the campaign was paused). But of course, the daily budget is still consumed.
That is to say, every day I paid x and received x contacts, suddenly I keep paying x per day but I receive zero contacts.
This happened to me every time I started a campaign.
It is important to clarify that I do not make any change in the campaign to make this happen (I do not change any match, I do not change the budget, nor the geographic area, I do not do anything different between when I received contacts and when I do not receive them).
What could be the problem?. Thanks for your help
