I decided nevertheless to report this problem to Apple using their bug reporting system. A few days later Apple requested more information which I provided on the same day. Yesterday they closed my bug as a duplicate of another bug. Working as a software developer myself I considered this a reasonable course of action.
But when I logged into Apple’s bug reporting system this morning I discovered that I cannot access the bug that my bug is a duplicate of. As a result I will never know when the bug will be fixed and what caused it in the first place.
Thank you, Apple! 🙁
