I have two mailwizz instances running. Both were running on 1.4.8 but one had the Sendgrid WebAPI option in delivery servers while other did not have. So I upgraded the later one to 1.4.9 thinking that upgrade may help but even after upgrade to 1.4.9 this one does not have Sendgrid WebAPI option in delivery servers. This looks like some configuration issue. Does someone has any clue ?
