I am experiencing issues with 6ghz band on my iPhone 15 pro. All of a sudden the 6ghz band disppears/appears/some times no visibile at all at often days and it was same since I purchased my phone and I have already logged a case with apple support for the same which is still unresolved. I am on iOS 17.1 stable. Does anyone else experiencing same on iPhone 15 Pro/IPhone 15 Pro max?
