To facilitate Design Sync, sites are automatically bound to the template used to create them. There are three situations where this may not or may no longer be the case:
See About BrightWork and SharePoint Security for information about the permissions required to bind a site to a template.
To manually bind a site to a template:
Note: Only templates of the type (e.g. Project Lite; Project Standard etc.) that were used to create the site should be displayed. If the site and template are from a previous version of BrightWork, it may be possible to bind the site to a different type of template; however, this is not supported or recommended.
