There are a few older topics on a similar theme, but I thought it might warrant a fresh thread after nine years.
Sometimes when sending a bill split at the end of the month, the repayment doesn’t arrive until the following month. It then appears as positive spend for that category, when it actually applies to the previous month’s spending.
The same sometimes happens with refunds which arrive a month or more after the original transaction. It has the same result of showing positive spend in a category.
Perhaps a solution could be to tap the inbound transaction in Trends and then a new “Assign to previous month” button. (Sorry, I’m no UX writer.)
To be fair I would like this with my salary - almost all banks/budgeting apps give me a negative in overall spending because I’m paid last day of the month so all my outgoings for that “pay” are seen as negative but no actual income until the very end of the month once I’ve spent everything.
