Thanks Sandip.
The “My Account Page” was left empty (the name is a bit ambiguous IMO), but choosing my login page from the dropdown solved the issue!
I am testing this on my other website https://villelaukkanen.com/register/ and the email NEVER comes through.
In the WP Dashboard – Users, status is “Awaiting Email confirmation”.
This after deleting and reinstalling the plugin.
Thanks Amrit, that seems to do the trick!
I will ask more about the premium product as soon as I get our email confirmation working. We need to get the marketing consent and T&C acceptance nicer, at least.
