I´m creating a register controller with Symfony 5.4 and when I use Symfony\Bridge\Twig\Mime\TemplatedEmail and ->htmlTemplate inside a mail with (new TemplatedEmail()) I always get this error message: Call to unknown method: Symfony\Component\Mime\Email::htmlTemplate(). I don't know what to do because when I register a user, I get the same message: Expected response code "250/251/252" but got code "550", with message "550 [E3] Message rejected because sender's email is not confirmed.". I don't understand why this is happening, the sender's email is confirmed so I suppose that this error is due to something related to the class Symfony\Bridge\Twig\Mime\TemplatedEmail, maybe I'm missing something. I really appreciate your help, guys, thanks
I have tried everything, I'm desperate right now so any help will be highly welcomed, thanks
