"The Apple ID you entered couldn't be found or your password was incorrect. Please try again."
With the correct password, I get that message while trying to make an in-app purchase. If I enter the password incorrectly I get "Your Apple ID or password is incorrect." This has been going on since about 10am central. What's up? I have seen this was an issue in the past years but not recently and no real answer was given.
