Invite user not working

Hi,

I’ve followed the Invite Only documentation (not yet any version that is viable for .NET Core though) but when the email is sent for the user to active the account the token is not present. Instead I get this

Account/Activate?supportSignUp=true&supportForgotPassword=true
&email=xxx%40gmail.com
&message=This%20account%20is%20already%20verified.&success=false#
