I think it would be a good idea if we were able to edit our expected direct debit dates. I have set up a pot and though I have changed the direct debit date with other company it does not update with the payment calculator. It still thinks payment is due on that set date. For our records. It would be handy to be able to edit the dates ourselves. I think this would be a good feature though monzo has many good features please add this option.
You will get an updated date and amount (if changed) a couple of days prior to being taken, anyway and to be fair I can’t see this happening frequently enough to be requested.
