Same here - Using the Galaxy Note 3 Samsung Phone... when accessing the android EN app - and selecting "add Reminder" then - tapping on the calendar to the right to set the date and time.... only the sliders work, if you use the arrow down menu and select from the dial for a future date or Time it will not save them.... I must only use the slider and or circle slider method. I have tried this - so who ever is watching knows... this is the case when logged in via Wifi - or 4G or standalone. I am running Android 4.3 (used to work on my old phone an HTC incredible 2 running old 2.3) same issue glaxy note 2 android 4.3
