I'm just getting started and love the component so far, but I am having trouble with loading lists or creating emails (campaigns).
When I try either, I will wait at least 5 minutes for the backend Lists content to load, and a little longer for the email template load!
Otherwise, I was able to configure SMTP server and send a test email quite nicely. There are no errors displayed.
This is a custom Linux PHP 7.4 server. Is that an issue?
