What does validation code not valid mean in signing up for unova rpg?

The "validation code not valid" message in Unova RPG typically means that the code you entered during the signup process is incorrect or has expired. This could happen if the code was mistyped, used already, or if there's an issue with the email or SMS delivery. To resolve this, double-check the code for accuracy, or request a new validation code to be sent to you.
