Apple releases iOS 13.1.2, iPadOS 13.1.2, watchOS 6.0.1 updates

I haven't even been able to get 13.1.1 and now 13.1.2?  I'll be waiting anxiously as I have noticed several instances of Bluetooth disconnects with my AirPods.  Also, since updating to iOS 13 my wife and I have noticed various trouble AirPlaying to Apple TV (initially at 12.4.1 but also under tvOS 13).  Hope this addresses those connectivity issues too.

I thought some inconsistencies were going on in the cloud.

I'm finding that iPadOS 13 isn't working as well when it comes to screen rotation.  For example, I can lift up my iPad and the screen is upside down.  I have to turn it to portrait and then back to landscape for it to be right side up.  I never had this problem with the earlier iOS releases.  I also notice that my mail works different than before.  My mailbox is full of spam, so I basically touch the bottom one and work my way up deleting them one by one (every now and then, I have some legit mail).  The new mail doesn't highlight each message as I delete them, but it shows the message in the right pane.

AppleInsider said:

Apple has updated iOS 13 for the third time in a week, and has rolled out iOS 13.1.2 to the iPhone and iPod touch, in addition to iPadOS 13.1.2.

The update follows hot on the heels of iOS 13.1.1, which was released on Friday to deal with a keyboard security issue and some other flaws. Monday's update deals with an issue with the flashlight, a bug that could result in the loss of display calibration data, a Bluetooth disconnect problem, and an iCloud Backup issue.

The update to iPadOS 13.1.2 lists two fixes. The same iCloud backup issue is listed, and HomePod Shortcuts problems have been dealt with.

Apple's watchOS 6.0.1 update resolves an issue where Disney's Mickey Mouse and Minnie Mouse watch face don't speak the time, fixes an issue where the calendar complication may not display events, and also deals with the potential loss of display calibration data.

Users can update to the latest iOS and iPadOS release by entering the Settings app, selecting General, Software Update, and selecting to install the update. If users have automatic updates available, this will streamline the process for them.

Is iOS 13 a rewrite of the 12 software? Why new version 13 has bugs that do not show up in 12? Does Apple test software internally? Why Apple has to update 13 twice in just a few weeks? This is very poor software quality assurance.
