So I want to develop a few add-ons for confluence and signed up for a free Development Cloud instance BUT, the billing part of the instance says I will have to pay $10 for Jira Service Desk, although in the terms of it said that there was chance for a single user to use it so I'm confused on how billing actually works on development instances that don't have a billing method set, especially with add-ons for Atlassian products and for Atlassian products themselves (Like Service Desk and Team Calendars for Confluence), Does anybody know how pricing for add-ons and apps work on a Development Cloud Instance?
