 If your password contains special characters, _pilot_ may throw a confusing error saying your "Your Apple ID or password was entered incorrectly". The easiest way to fix this error is to change your password to something that **does not** contains special characters.

+If you are on multiple App Store Connect teams, iTunes Transporter may need a provider short name to know where to upload your binary. _pilot_ will try to use the long name of the selected team to detect the provider short name. To override the detected value with an explicit one, use the `itc_provider` option.
