Calendar events disappeared after iOS 27.0.1 update

I updated my iPhone 14 Pro to iOS 27.0.1 two days ago, and the morning after the update, my calendar events were still there, but last night I went to check the time of an appointment for today and saw that all of my events were gone. This is extremely frustrating, especially because I ended up missing the appointment this morning due to this. I have tried toggling the "Use on this iPhone" on and off multiple times with no results. I've changed Sync from All Events, to Events 6 Months Back, back to All Events, and nothing. I even went online to iCloud restore, and it says the oldest archive was last night at 07:59 pm and it's compeltely blank. I know I was using iCloud calendar because it always gave me the option for "work, home, and calendar".


I have read of some people losing their calendar events when they were low on storage, and I will say that prior to the update, my phone kept telling me I had no storage available. I did clear storage, and noticed that after the update more space became available, but as previously stated, this calendar issue happened a whole 24-36 hrs after the update. I am even trying to clear storage now in hopes that my events will reappear. If anyone has any other tips or advice please let me know!



iPhone 14 Pro, iOS 27
