I actually like this app which is the reason why I subscribed to the pro version. However, ever since then, the app keeps on reverting back to free (and constantly tells me that I do not have a valid purchase when trying to restore purchase) so I have to uninstall then re-install for the pro features to work again. Plus! I had to assign each categories from scratch (from months back) because it does not sync the categories either. It is very tiring. If this a bug, I hope that it gets fixed.
