Time to Leave notifications stopped working on my iPhone

Hello Jon,

Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are having an issue with Time to Leave notifications for events in the Calendar app, even after trying some good steps. At this point, we would like you to reinstall iOS on your device; this will help us isolate the situation further. Reinstalling iOS should not affect any of your data, but it is always a best practice to make sure you have a current backup in either iTunes or iCloud.

How to back up your iPhone, iPad, and iPod touch

Transfer photos and videos from your iPhone, iPad, or iPod touch

Once you have a current backup, follow the steps from the "If your device turns on but gets stuck during start up" section in this article:

If your iPhone, iPad, or iPod touch won't turn on or is frozen

Use the “Update” option and not “Restore” and these steps will reinstall iOS. Keep in mind that these steps were written for a different issue, but they will still help us isolate the situation further.

Cheers!

Thanks for replying, Jon, and that additional info, it really helps! Next, use your Mac or PC to backup and restore your iOS software to factory settings, as this process erases the information and settings on your device and installs a fresh copy of the latest iOS software. Temporarily set up your phone as new to test your issues, and then restore your back up and test the issues again.
