For some reason, none of the calendar apps I have tried will sync properly with any calendar on the web. Yahoo Calendar used to be my default, but Yahoo made a mess of it.... So, I switched to Gmail/Google Calendar. I am currently trying 'UpTo' and 'Jorte Calendar' and neither one of them will sync and display anything that is created on the web Google Calendar. both will post an event to Google if made from the phone, but the reverse never works for me. I have looked for 'Sync' and can't find it in Settings anywhere. I looked at both apps in Application Manager, no mention of Sync there either. In Jorte, you can force a sync but it does NOT retrieve anything from Google Calendar. In UpTo you can't force a sync. I looked at sync in each app's settings, turned it on.... to no avail. this is frustrating, and really nullifies the value of even having a calendar app on a phone. Surely, there is something I am not seeing thru the mist here.... FWIW: in the past I used a Samsung Galaxy S5, and now I am using a Samsung Note 4... no difference, neither will sync to the cloud.
