From our side, the rai_node was super duper overloaded of deposits and withdrawals. That means that if usually it takes 1/15 minutes, now it may take up to 24 hours due to the pending transactions (see about the pow).
Even though this process is automated, the chain and the node needs time.
The only thing to do is to wait
What's the thought process & progress on scaling this up as adoption grows? I can only imagine how much worse it'd be if the RAI market grew by 50,000-100,000 people.
BitGrail can use more powerful server or optimize receiving proccess (now it require 3 transactions instead of 1 - exchanges somewhy prefere resend all to 1 central account) or there will be external paid PoW generation services (or may be add option to core wallet to external PoW from other network nodes for optional fee).
