I am having this problem today with opera and opera gx, both not saving the newest session tabs but reverting to the one before. What I mean is when I watch youtube and have 3 or more tabs it saves normally but then when I resume this session any changes to the tabs is not saved.

I have deleted and reinstalled opera and gx and the same problem remains.

@leocg I tried the suggestions but sadly neither fixed the issue.
