After reviewing this issue with my client, they have determined that the workflow requiring users to log in manually after registration is a deal breaker
So… I have to create some type of a work-around while we await a stable release with the CB Subs trigger location you noted.
Since this only occurs at registration I am thinking that I could pull the email and password values at registration and assign them to custom cb fields.
Could I then post those cb field values when the user hits the thank you page to somehow automate a redirect that log the user in for the first time?
Any other “out there” solution that I can attempt would be greatly appreciated.
