updated to 14.4 a couple of days ago from 14.3 - ever since then i cannot access internet on iphone 12. I can reproduce the issue by turning off wifi, then safari and everything else cannot access the internet. Phone calls work ok, and sms etc. And its not just my phone, my wife has an iphone 11 with the same issue. Can anyone suggest a fix or advise what is going on with 14.4?
