It (13.1.1) dropped on my iPad mini4 yesterday evening, usually I wait a few days but figuring this was a small fix I went right in.....It was already downloaded so it went to 'Verifying Update' then to the & progress bar which advanced to about 1/2 " and stayed there for over an hour...I left it and came back awhile later and the update was done....I'd done 13.1 a few days ago with no issues on this or the other 3 devices in the house. I hadn't done 13.0 and have never done any Betas. It has yet to drop on the iPhones, or my wife's iPad Air2...i think I'll hold off a bit (as I usually do..) We have used SwiftKey on al devices for years thus as I heard (?) that this update relates mainly to security with 3rd party Keyboards, once it drops, I may A/ uninstall SwiftKey, do the update, then B/ reinstall the keyboard
