Set alerts on calendar
I have an iPhone 10. The alerts keep switching when I set the 1st and 2nd alerts. Ex: first alert set for 1day before my appointment. Second alert set for 30 minutes before the appointment. After pressing “Done” they switch. First alert becomes 30 minutes before. Second alert becomes 1day before. They won’t stay correct. Very frustrating! And they won’t alert me for my appointment. If I set only the first alert w/o a second alert then I will get the alert. Help!!!
iPhone XS, iOS 12
