Have purchased a new Mac and am in the process of migrating to it. Although I can install and use Opera properly, it will not allow me to properly synchronise with my account. Following instructions here:

https://help.opera.com/en/opera36/sync-your-browser/

I should see an advanced configuration section with the ability to enter my passphrase. For some reason, however, that option is not available. As a result, I am unable to fully login and begin the sync process. Am I missing something here? Is it possibly turned off somehow?
