On my iPhone and IPad I have 30 items on my Today list. If I use the website or teh Windows app, I only have 18 items on my Today list. None of the items that were scheduled to start today are appearing on my Today list on the PC. If I use calendar view to look at scheduled items, they are all on Today's list, although a number are duplicated even though they are not duplicated in list view. Synchronising between devices appears to be working OK. I am using 3.9.10 for iOS and 1.5.9 for Windows.
