A strange bug in iOS is causing the Clock app to crash when creating a new alarm if the device’s timezone is set to Beirut, Lebanon. The bug is believed to have started with iOS 14.4, which was released in January. Apple users in Beirut have reported the bug to Apple on February 23rd and received a response from Apple Support on the same day. Unfortunately, the bug persists into the next iOS version, which is March 8th, 2021. Apple is aware of the bug as a user on Twitter have reported it to Apple.
