I think the new Vaults feature is great. Especially the Spare Change feature that rounds up your transaction to the nearest whole number.
However, today I made a transaction for exactly 1€ and was VERY surprised to find that another €1 was paid into my Vault!
Clearly this is some sort of bug in the logic being used to calculate the amount to round up. I don’t know if it only happens if you spend exactly 1 currency unit, or if it happens when you spend any integer number of currency units.
Any chance you can get QA to have a look at this?
