It is likely due to the type of account you and your co-worker have. The Foxway demo apps are only visible to certain account types (similar to your account). If you'd like to share your co-worker's email address, I can check their account type. It's probably best to share the email address privately so that it is not visible on the forum.
1. What type of account do I have?
2. How do I share my coworker's email addresses privatelt with you?
Please feel free to share information privately to the feedback email address: firstname.lastname@example.org
I will share your account level information along with the reply in the private email.
