I push the alarm clock symbol on the time I want to wake up and then it turns blue. Also the alarm clock symbol appears on the top right. it also shows the time it is set for on my lock screen. BUT. In the morning i wake up and notice my alarm never went off. it still shows what time it is set for on the lock screen, and shows that the little alarm symbol is still blue. HOWEVER, the alarm symbol is not at the top on the right anymore. PLEASE help! this is a major issue for me!!!!
