Hi there, I split my first bill in a restaurant with a friend also on Monzo. The bill came to £24 and split with the friend. The friend then paid and it showed up as a £24 bill with a £12 received fee from a friend as seperate transactions. If you’ve split a bill with a friend, that bill should change from the £24 to £12, and when clicked in should maybe say total for bill was £24 and which friend paid half, but ultimately just want to show the bill to me as £12, not £24 and a -£12 later, as that skeews my spending.
Also, furthermore, I went on holiday with my gf and I used my Monzo card abroad the entire time and she paid me back via Monzo, you should be able to attribute incoming money from someone against a bill/transaction/holiday and it update your monthly spending accordingly to what “I’ve spent” not what the total that was actually spent.
