Tried the first 2 ways to get the email addresses for gmail, says:
There is a problem with your email address. Please verify that it is spelled correctly. If it is not, please correct it and try again. If you already have a Pokémon Trainer Club account with this email address, please use the Forgot Password Tool to find your account.
Typed the original I’d and added +01 before @gmail. Did they fix this so it cannot be done anymore?
