I know that the sandbox only sends mail out to mailinator addresses, but can they be validated after?
"Thank you for verifying your email BB35D120-0D13-4FDB...@mailinator.com
" from the sandbox webpage
however, when I go to 'developer tools' I. see the "Verify your email address to get started" button.
Am I missing a restriction? found a bug using UUIDs? something not respecting case semsitivity on the local-part of the mailbox?
This feels like I'm making a very trivial error
