Following official upgrade to 10.2.0.424 on a STL100-2 the "Due date" is completely ignored. I have asked previously whether anyone else has the problem and apparently not. I notice in the "help" video for the app that there is a button to turn due date on/ off- I do not have this button but just tapping on due date lets me set it. The app tells me when a task is overdue so it obviously recognises the date but it will not order my lists to Due Date - they just remain alphabetical. Does anyone have any ideas that I could try? I am reluctant to restore factory settings and reload the OS as there seems to be so many horror stories around and I do not seem to have any other issues. As I use this app a lot any suggestions gratefully received.
