Hey there,
Using Qlik Application Automation I've seen that Send Mail block still requires you to set the SMTP configurations... Even if you've already set those on QMC.
It's not mandatory (and possibly it's even a remote condition in a Production environment?) to use the same credentials for both scenarios (QAA and regular Qlik Sense's mail purposes), but for testing scenarios it would be really helpful having those credentials already there
Let me know what you think,
Riccardo
