Don't Install iPadOS 13.2.3 If You're Jailbroken
If your tablet is currently jailbroken or you think you might want to jailbreak it in the future, you'll want to avoid iPadOS 13 and iPadOS 13.2.3 for now.
There is currently no way to jailbreak a device running iPadOS 13 and we have no idea when or even if developers will release a tool for Apple's new operating system.
Jailbreak developers have teased iOS 13 jailbreaks several times, but there's no guarantee one is released for iPadOS and the general public.
If you want to jailbreak an iPad, it needs to be running iOS 12.
