I have an issue elated to syncing of content between sites, one is in en-ca (default) language and other two in en and fr. But we need syncing between two english language sites, hidden link is in en-ca and hidden link is in en.
Solution: You can use the Duplicate option to duplicate the content, and if you make changes in the original you will need to update the translation as well. Otherwise you can use the option "Translate or Fallback to default" and then, if there is no translation available, the default langauge content would display for the secondary languages.
