I am trying to use the new event registration marketing form on a custom azure web app. It works just fine when the registrant count is less than the Maximum capacity, but when the registration count equals the maximum capacity and the wait list is enabled, my app will receive a 404 error if someone tries to register. I tried registering for the same event in the out of the box marketing event portal, but the same marketing form worked as expected and created a wait list record instead of a registration record.
Will the new forms support waitlisting in external marketing websites?
