We get this concern once in a while and many times there is actually nothing wrong, we have just optimized for the minimum number of payments, For instance, if John owes Linda $5 and Linda owes Fredrik $5, Steven will simplify the calculation by showing that John owes Fredrik $5. That way there is only one payment instead of two but everyone still gets even.
If the numbers doesn't add up, that could be because all participants haven't been added to all expenses. We recommend that you check that all expenses have the correct information added.
If you still suspect that something is wrong with the amounts, please reach out to us via the support chat in the app.
