Thanks mate. That’s what I’m doing but it says my software is up to date. It’s currently showing iOS 12.0. I want beta 3 though.
First off...it’s public beta 2, not 3.
Second, if it already updated, it will still say iOS 12.
You’ll need to go to “general” and “about” to see which build you have to verify if you are still in beta 1 or if you in fact already updated to beta 2.
