On my old laptop, I went to sync.opera.com and it shows all the types of info synced.
It does show the question re: key synchronization password and if I need to reset it - not sure if I ever set that up? Nothing is asking me to enter it though.

Do I need to have the same sync parameters setup on my new laptop?

I dont understand what is supposed to happen. I signed in to my opera account on my old laptop and setup the items I want to sync. Appears to have been saved.

Went to my new laptop and signed into my opera account. Nothing there. Nothing to indicate a transfer is occurring.
