Yes ... more likely it's like that ... makes sense.
CRA used to be the same way in the past ... firstly we could pay CRA with credit card .... and then we couldn't ...
But ability was still shown there ... and some people were still implying that we could use credit card to pay CRA ...
But once one tried to actually pay it (not just see credit card bill payment method still showing for that biller) -- they were denied .. and message appeared that they could only pay that biller with a bank account, ... and not a credit card.
