I've ran an experiment for this demographic at ACCELERATED, MANUAL BID @ 2.25 for each CPC.
I've also done the same for ACCELERATED, MANUAL BID @ 5 for each CPC.
Now that I am actually launching an identical campaign, I get my ads "approved" but then I don't see any stats whatsoever (everything is zero).
This happens every once in awhile. This is not the first time that I've seen this happen.
I've tried changing upping my BID AMOUNT, turning each ad set off and then on again, but still nothing works.
I've even gone as far to duplicate my campaign with no success.
Any ideas what is happening?
EDIT
This is a screenshot:

In most cases the Facebook bots spotted something suspicious due to you using a specific terminology. This is usually followed up with a manual review.
Another potential issue could be due to you making too many campaigns too quickly, or scaling up too quickly. You must be very cautious with Facebook.
Best of luck!
You should look into the graph result for the campaign, your campaign more than likely has the "has_error" property set to true, which either means Facebook crons have not allocated the serving frequency for your campaign for the day or your campaign is in a "ghost review".
After you deal with this, your accounts will begin being redboxed for "RISK_PAYMENT", the generic status they use to disable aggressive accounts. Have fun!

I am trying to figure out what fields I have to submit to get the has_error field out.
I found this page: https://developers.facebook.com/docs...y-target-spend
However, I believe this has been deprecated in 2.7.
If I guess correctly you are querying graph.facebook.com/<campaign_id>/insights for this information right?
Yeah `today_target_spend` has been deprecated.
`graph.facebook.com/<campaign_id>?fields=id,today_target_spend,click s, spent,effective_status`
{
"error": {
"message": "(#100) Tried accessing nonexisting field (today_target_spend) on node type (AdCampaignGroup)",
"type": "OAuthException",
"code": 100,
"fbtrace_id": "FrP1xmiZHnC"
}
Does anyone have any other way of figuring out if your campaign is under review?
If traffic will not start within the first hour or two, you'll probably under review. Happens mostly on newer accounts.
If your approved to disapproved ads history on that account is really high, usually your ads will go active immediately and review would only be triggered by bad social feedback. And even if they don't go active immediately and they show as "pending review", if your account history is really good, they will probably go active after a few hours with no manual review from fbook even if they say the ads were under review in the first place.
Also. If an overwhelming majority of your adsets show really high CTRs (Relevancy ad Scores 8 and above), fbook will automatically "disapprove" one or couple of your adsets or stop sending them traffic altogether (like they have been disapproved). In that case, simply delete those adsets and re-upload them with a slightly different link, from mydomain.com/imcool to mydomain.com/imcool2. This will do the trick and they'll start sending you traffic on the new duplicated adsets that had previously been disapproved.
