I downloaded iOS 15 Beta 4 but found that all incoming calls were going straight to voicemail. So I went back to iOS 14. Problem persisted so phoned Apple who talked me through the usual checks but could not see anything wrong so I contacted my carrier who gave me instructions to fix the problem. So now all good.
Question is, should I try iOS 15 again? Not sure if it was causing the problem in the first place? What do you guys think?
I have the patience of a gnat. Downloading again! Wish me luck….
