That's shorter than expected — default sessions should last quite a bit longer than an hour of active use. Getting logged out that frequently usually points to either a browser extension clearing cookies on a timer, or the system clock on your device being noticeably out of sync (session expiry is time-based, so a fast clock can make sessions look expired early). Can you check your device's date/time settings are set to automatic, and try disabling any privacy/cookie-cleaning extensions temporarily to narrow it down?
