@dragonking97 Thank-you for the response but while this is similar in the sense of being 'logged out' its only my Opera account I am logged out of. I stay logged into websites I choose to stay logged into. The result is I can't keep my 2 computers' Opera instances synchronized. History, bookmarks and passwords are effected.
There used to be a way on the opera://sync-internails page to force a synchronization i.e. 'Sync Now' but the developers decided to remove this functionality. I can only hope they reinstate it which they have done with other functionality in the past.
