On iOS payment references used to be stored so you could select them when you went to make a payment, but since a recent update this is not the case.
This is a massive backward step as for some payments like cards or transferring to building societies/savings accounts you need to enter your account number as a payment reference. It means you now need to find and manually enter this each time as opposed to it auto-populating or you selecting a previous one.
Please put back the functionality or sort the bug on iOS if it is one.
Thanks
