When does Bilt pull money from my checking account for mortgage

I made the mortgage payment on 2/27 Friday using the routing and account number Bilt provided, and set it to charge on the Bilt card. My understanding is Bilt will pull the money from my linked checking account to cover the mortgage payment. Today on 3/2 Monday, I saw the mortgage payment is successfully applied to my account, but I don’t see any mortgage payment record on Bilt and it’s not pulled from my checking account yet.
