"sorry, we cannot process your request" after entering CORRECT verification code
When I tried to login to the Apple Support Communities using safari, or firefox, it refuses to recognize my MacPro computer and sends a verification code to my iOS devices, and to the very MacPro desktop computer that is running the browser (explain that?!) The code sent to each of my devices is different than the code sent to the other devices. I click "allow" on a device, and then enter the verification code presented on that device, and constantly get the "sorry, we cannot process your request": regardless of whether I use the verification code presented on one of my iPhones or the one that pops up on the Mac Pro Desktop itself. I finally got so frustrated that I went to appleid.apple.com and shut off the two factor verification. Anybody have ideas on why the two factor verification codes are not accepted when using Safari or Firefox?
