When new people are added to a running split, the split doesn’t automatically give you the option to add the new person to transactions that were added to the split before they were.
E.g. say I have a running split with a few friends for buying birthday presents for someone, and I add a few transactions. Then I find out someone else wants to contribute, so I add them to the split too, but now if I go back to edit the transactions I’d previously added, I can’t include the new person, meaning I have to delete the old transactions and re-add them in order for the new person to be included.
It would be nice if this could be adjusted to make the splits more user-friendly!
