Apple Seeds Third Betas of iOS 13.3.1 and iPadOS 13.3.1 to Developers [Update: Public Beta Available]

Apple today seeded the third betas of upcoming iOS and iPadOS 13.3.1 updates to developers, one week after seeding the second betas and more than a month after the release of iOS 13.3 with Communication Limits for Screen Time.

iOS and iPadOS 13.3.1 can be downloaded from the Apple Developer center or over the air once the proper developer profile has been installed.

iOS 13.3.1 includes a "Networking & Wireless" toggle that turns off the U1 Ultra Wideband chip in the latest iPhones. The feature, located in the Privacy > Location Services section of the Settings app, turns off location for Bluetooth, Wi-Fi, and Ultra Wideband.

Apple added this location toggle after it was discovered that the iPhone 11, 11 Pro, and 11 Pro Max continue to track user location even when location services options are disabled. This is because there are international regulatory requirements that mandate the U1 chip be disabled in certain locations.

The new toggle makes sure location tracking is off for the U1 chip at all times. Apple has also added a new "Play Again" button when replaying content that you've already watched in the TV app.

Along with these features, the iOS 13.3.1 update also likely includes bug fixes for issues unable to be addressed in the iOS 13.3 update. Specifically, it could address some issues with Communication Limits, fixing a workaround with the Contacts app that allowed children text someone who contacted them from an unknown number.

Has Apple fixed the problems with Catalina's Mail application?
They definitely haven't fixed Catalina Mail issues in this iOS update.

Why create a separate toggle rather than simply not ignoring the user's disabling of location tracking?
Used for different purposes so it makes sense to have separate toggles

iOS 13.3 is STILL killing apps in the background almost immediately!

Examples are Amazon app, Google Photos, Whatsapp wont do its daily backup overnight, etc!

Most of apps are refreshing even freakin 10 seconds after they where closed, only one app opened between them.

WHAT THE HELL!? I’m not seeing apple or communities following up on this.

It’s definitely NOT resolved. Anyone!?
Definitely huge issue. It's embarrassing.
