Just like whatalexdale said. You have to wait. They have to process thousands of checks and everything else. You just have to be pacient,
I have a 'payment issued' note today! I'm receiving payment via cheque, though, so it might be a few more days before I actually deposit the funds.
Still PIP here in the Philippines, same with Singapore. [godmode told me] But payment issued usually shows on the 27th so its still acceptable atm.
