Finally paid as well. Looks like we were in the same batch.
Affiliates are paid once a month. Payments are processed on the 15th working day of the following month. Affiliates must meet a minimum payment requirement which is set at $100. If you do not reach $100 the commissions are carried over to the following month, until this level is reached.
We should have to wait until the 27th to be paid. Even taking into account the Easter public holidays, these payments were still late according to my calculations.
