To add or change an App's Developer information you must first be in the 'Configure' section and scroll down to the 'Developer' Template. Once there you can set the Developer information:
- Which Person or Team, is responsible for the design and development for this app?
- Does the individual / team have an associated web address?
If desired you can link a specific User of the site to the development via the drop-down.
Make sure to click the 'Save' button when making any changes in order for them to be added to the next app version. Once you have made all the changes you need to an application you are then ready to publish it to workspace.
