Got an email this morning from FB ads team saying that one or more of my ads violates FB's guidelines or TOS and how if I continue to violate my account could be disabled, etc etc. However none of my ads have been disapproved? I got this email immediately after I changed my targeting on one ad. It went into review mode, and then I got the email it was approved. One minute later, I got the warning email. But like I said, this ad, as well as others are still approved. Has anyone ever had this happen to them? Would they leave the ad running even after giving me a warning?
