I found the following question and I have the same problem. However the answer that was posted did not work for me.
I have a field("Comments") that is a type text box and allows multi-values. When I use the Comments token and use it in the body of the email, it just includes the 1st value. The succeeding values do not get included in the email even if I have the retrieve values process before it.
How can I include a multi-value text field in a body of the email?
I have tried everything that I can think of and nothing seems to work.
