@Machiavelli Your payment hasn’t arrived yet because it hasn’t been sent. Before posting, you might have noticed the banner at the top of the site that looks like this:
Payouts begin around the 7th of each month. The first few days are for reconciling ads, and then payments start being sent out, which can take some time.
How long does it take to arrive? It varies—from a few days to a few weeks. They do push out payments as quick as possible and it usually arrived within a few days of when payouts begin.
All the browser is saying is that the payouts are beginning as it is the scheduled day. You can always track the status of payouts at Ads Payout Status Update which is the big banner that they have on the page here.
