I would prefer not to do it, but I can give you a detailed description:
I have 4 accounts (e.g. mine and that of my wife) for earning and spending. In addition, I have a couple of main categories, like earnings from language teaching, from IT, from consulting etc. If I do not any filtering, all my entries are shown in the reports. But if I do any filtering, the outcome cannot be predicted. E.g. If I exclude the account of my wife, nearly all of my own earnings and spending disappear. There are many other similiar strange behaviours. It seems to me that the links between accounts, main and subcategories are completely mixed up.
It's really a pity, it's otherwise one of the best pieces of software for Windows Phone which is nearly unusable now due to not working reports. I wished I could return to the next-to-previous version.
