iOS 9.0.1 released. Improved problems such as alarm not sounding

iOS 9.0.1 has been released quickly.

The contents are as follows.

• Fixed an issue where the setup assistant might not be able to complete after an update
• Fixed an issue where alarms and timers would sometimes not sound
• Fixed an issue where paused frames would appear distorted when pausing a video in Safari or Photos
• Fixed an issue where setting a custom APN using a profile could result in mobile data loss

It seems like the main focus is on bug fixes.

I feel like it's quite an easy mistake to have an alarm or timer not go off...

Well then...
