Ok, so I've contacted adwords support to figure out the reason behind not displaying my ads, though they were displayed yesterday... They still show as "Active" despite not receiving any new impressions this whole day. Here is their reply: "Hello, I understand you're concerned about the visibility of your ad. It appears your account is under review. We periodically review accounts for security purposes and to verify billing information. I'll consult a specialist team regarding the status of the review and will provide you with an update shortly. We sincerely appreciate your patience." Ok, so how long does this usually take? I've still haven't heard back from them for a whole day. .
