I'm running Opera One(version: 104.0.4944.36).
Been using advanced Sync since it first became available for Opera, and have now found that following a replacement of a failed hard drive all of my bookmarks, passwords, settings etc have been synced to my new installation, however the ten speed dials I had on my old machine, consisting of over 100 bookmarks, have all disappeared.
This is a major issue for me, and may well become the stumbling block for recommending Opera to my clients and friends. I am a Senior Support Engineer with over twenty five years experience and this is the first time in my life I have had to raise an issue like this to a forum.
