Could the Dev team consider allowing customer choice of the favourite currencies, or push currencies that have funds to the top?
Situation today: select Exchange and you are asked to choose currency. But only the legacy currencies appear (£ € $).
I hold funds in ZAR, which I use regularly, so it would be a favourite for me. I must select OTHER then scroll the screen to ZAR (or type in the search box).
It would make more sense that the app offer all currencies that have funds first.
