Facebook Audience Network not accepting new payout registration

Consider this a PSA if you are planning to buy the FAN plugin(maybe try the free one first) and it’s not an isolated incident to me.

I am having problem with one of my apps running banner using admob, so went to test Facebook ads. But as the title implied, Facebook is not currently accepting new registration for payout thus making it unusable (confirmed it with their support). AFAIK, if you already registered you are fine.

Cheers
