@opera-qa-team: yes, it happens all the time. And also on different installations. Yesterday I was testing a new installation (Fedora) and got the same issue.

I am using the SNAP package on both. Can you eventually test if the issue is related specifically to that?

After the last update (in Linux), Opera is not retaining the open tabs anymore.
I confirmed the settings are correct ("Retain tabs from previous session" option is selected).

Anyone else?
