@burnout426 1) opera://settings/clearBrowserData. In Basic tab: All checks are unmarked except of "Cached images and files", selected Time period: "All time". Advanced tab: All checks unmarked, time period: "All time".
2) opera://settings/cookies. "Block third-party cookies in private mode" is selected. No other specific settings were not changed/setuped there.
3) I don`t press Delete button, simply chose "Time period" and closed by pressing "Cancel".
4) Date, time, etc are correct, opera sync is not used.
As for cookies that expire, I`m not sure, I have tried to view them on the example of google, but there are a lot of them, I failed figuring out which one is session cookie. Some of them indeed have expiration date of short period (e.g 26.12.2023 ; 01.01.2024), while some till 2025.
I will wait some time, last time i was logged out from all sites on 10.12.2023, probably some logout date will be same as in cookies expiration date. But what disproves this theory is that it logs out from not just one, but all sites.
(When on opera://settings/clearBrowserData Time period was selected "4 weeks", I got logged out approximately once a month, I never pressed "Delete" button.)
