Just my feedback:
I was extremely excited to see the Bank Transfer feature in Emma, but soon realised it wouldn’t be useful to me because of the £3,000 limit in Pro.
I have my salary paid into a traditional bank account - I then transfer it manually to a challenger bank account (I prefer manual because the amount I transfer isn’t always the same). I have a credit card that is paid via direct debit from the traditional bank - and so throughout the month I transfer bits from the challenger to the traditional, when I spend on the card. Along with Emma, this process helps me keep on top of money.
Unfortunately the £3,000 limit is just too low to transfer back and forth. If there was no limit then I would almost certainly stay within Emma for my transfers - I would definitely prefer this.
