Audio for headphones, via Apple lightning adaptor, stopped working on IPhone 13 and 13 Pro after updating to 26.1 and 26.2.

As soon as my wife and I updated to the IOS 26 series...we have tried 26.1 and 26.2... we can no longer listen to music or podcasts unless we use the speakerphone, which of course is not doable 90% of the time (office, gyms, airports, restaurants, etc.). We have tried two different headphones, on both phones (IPhone 13 Pro and IPhone 13), and neither will play audio. Yes...we are both using lightning adaptors purchased directly from Apple. This has to be a sofware problem from Apple. How in the world does such a massive mistake slip through Apple QA? What is the time line on a fix for this?
