Just trying out Forms for Confluence (using the Confluence Mail Server) & the forms I created do not seem to be submitting.
I have checked that Confluence mail server is working. There is nothing in the error queue either. The issue appears to be with Submit button not 'firing', but I am not sure how to diagnose.
I have created a Form Configuration with the recipient as myself. I have noticed the "collector" is "Email Relay" but there is no option to change this.

Then I have a Confluence page with a "Forms" macro (using the Form Configuration as a destination)
Within the Forms marco I have a couple of fields (Datapicker, Dropdown x2, User Picker.

When the submit button is clicked it says "Submitting" and then it just hangs like that

Appreciate any help on this
