Hi Sally,
Unfortunately the order of the bank accounts is determined alphabetically and this order relates to a number of other areas within the app so is unlikely to be changed i'm afraid.
Can I suggest that you name your bank accounts accordingly so that they appear differently in the alphabetical order? For example, using an (A), (B), (C) system?
I would also love to sort the bank accounts. I get that you can add letters/numbers to their name to effectively do that but it's not the most elegant solution.
