I have been making some minor changes to the reporting code in the past weeks to clean up some errors that were being thrown but I don’t believe they should have affected this report in this way.
I just ran a P&L report with the current build of Tiller Labs on two personal spreadsheets—“all accounts”, “last quarter”— and they both ran fine.
Is it possible there are issues with the way your dates are input in the Transactions sheet. Can you try applying the formatter “m/d/yyyy” to the Date column in the Transactions sheet?
This is a puzzle, @ros.
P.S. Sorry I missed your post the first time around.
