In the former app I could find the balance of an account on a certain date by sliding the balance graph around, in the new version that doesn't work anymore. Is there another way? I need this to check the balance of my business account with the numbers in my accounting software.

Actually in the end found a solution myself. The way to do it is to export an account statement for a period ending on the desired date (the lightning button, then choose to export an account statement, 'Exporteer een afschrift' in dutch. It isn't the easiest solution I could have thought of, but it works. If there's an easier solution I'd still like to know it.
