I apologize for tagging dev team members directly, but we all need some troubleshooting steps to follow here.
I for one have successfully set up MailGun, I got the correct domain name according to MailGun support and I am using the correct MailGun API key and when testing the email send-out to myself as a test member – it all works.
That said, I am still unable to change the support email address. It gives me a green arrow indicating that a confirmation email has been sent, but no email is received. Not even in the spam folder.
Furthermore, I have edited the
config.production.json file with the MailGun settings for SMTP and as explained, sending out emails when publishing posts works fine.
Not sure what or how to further troubleshoot this. Perhaps @Kevin can be so kind and assist?
