There are two issues here that Lee and I are addressing...oh and BuddaBoy also.
First issue is when someone creates an account...but DOES NOT buy immediately, you can not act on their behalf in the Admin Panel.
Path is - Sales>Customer>ActOnBehalfof when clicked takes you to the log in page, instead of into their account.
Also following that path, if you click on the Edit icon the Act on behalf of Orange Button it also takes you to the log in page, instead of their account.
Once that customer has made a purchase, all works well. So in summary, no transaction - no access to their account in admin panel.
It would be helpful if we could access their info, helpful from a customer service aspect, if they call and want to change info or have input a bad email address, for instance.
