This morning I updated both the Android system (now v. 4.3) and my Samsung account (now v. 1.5.0324) as prompted. I use Samsung's calendar app (the green and white one) and have it synced up to my google calendar. When I oppened the calendar, it was no longer displaying anything I had input under the google calendar and there was no option to add it. When I go to All Callendars there is no option to check my google account as there was previously. What's worse is I don't think it had actually been syncinc to the Google calendar for the year I used it, because none of my recorded appointments made it back online. It must have just been recording them through the app. and now they are just gone. I am a grad student and am currently freaking out because every due date and meeting is now gone. If anyone can help me I would be immensely grateful.
