After updating to iOS 18.1 beta 4, my iPhone encountered a major issue with Safari, where I am unable to use Safari, cannot connect my iPhone to 3uTools, and experience problems with login authentication.
Big problem with ios 18.1 beta 4
Also you can't go to any other browser, synchronization works somehow wrong and beta profile is missing from settings
I am also seeing this. Cannot successfully log in to my Apple account on my iPhone 18.1b4, or on my Apple Watch.
and, can’t send feedback because I can’t log in to the feedback app.
