When using the variable #UnsubscribeLink# on Mailing Lists in v16 it is displaying the Friendly Unsubscribe name properly but the URI that is auto-generated is apparently incorrect as it redirects to the following 404 - Not Found Error:

 

/Interface/errors/404.html?aspxerrorpath=/public/list.aspx

 

The #UnsubscribeLink# that is being auto-generated is as follows:

 

https://#WebmailURL#/public/list.aspx?action=unsubscribe&email=subscriber@theirdomain.com&domain=mailinglistdomain.com&list=mailinglistname@mailinglistdomain.com
