I haven't used Opera in 8 months because it seems they turned off the sync feature in. V12.16 and so I do not have easy access to my bookmarks and speed dials that are for work purposes when I switch to other devices and computers. I have around 25-50 speed dials that I needed quick access to as they changed regularly it has messed up how I work hence why I have had to go elsewhere.
Opera Link is still working fine for me on 12.17.
They certainly haven't "turned it off".
