Not the best answer you'll get but my experience in the past has been that once you put your device on the "beta" cycle (iphone, mac, everything else), they will follow that until you hard reset it...meaning once the OS goes general release, you're still on the beta releases.

This means you're probably already using latest Catalina on the device that's on the beta cycle and you will continue getting new minor releases before the general public release one.

Is it possible to get off beta cycle without "destroying" the device? iPad also shows beta 13.2 available but I stopped it from upgrading and would like to "downgrade" to regular iPadOS.

This page shows you how to unenroll from the beta programs for the various OS’s.

Then after that just go to the App Store, search for Catalina, and install it.

Perfect, that worked fine, iPad instantly turned to official iPadOS 13.1 and Catalina release could have been downloaded from the app store. Thanks!
