Expect IOS 13.1.3 to come out within the next week, mainly focusing on bug fixes, there are so many bugs despite 13.1 / 13.1.1 / 13.1.2 getting released, they haven't even fix half of the serious issues that plague IOS 13. I wouldn't be surprised if even IOS 13.1.4 gets released before IOS 13.2 comes out, it probably explains why Apple hasn't release the beta version of 13.2 yet, focusing on the bug fixes first before even thinking of 13.2. IOS 13 is a mess especially if you have went a spent big money on purchasing the new iPhone 11 Pro / Max only to be disappointed by the software.
