"Fulfilled jobs income share" option does not work

I hired Krill with a “Fulfilled jobs income share” contract. I entered “70” as the amount on the contract creation page, which shows up as “$70.00” after creation on the page with the list of all contracts. Krill accepted the contract and has performed a few jobs for me over the past week, but hasn’t gotten paid anything.
We understand the payout is at 00:00 UTC but there still hasn’t been any payments even days later.
