If one browser shows stale content while another works, try a private window or a targeted reload first. If that resolves it, cached files, extensions, or stored site data may be involved. Clearing only the affected site's data is less disruptive than wiping the entire browser.
Before removing site data, expect to be signed out and check whether drafts or local settings are stored there. If the same failure appears on several devices and networks, compare official status and community reports; a broad service issue will not be fixed by your cache.
Change one thing at a time so you can tell what helped.
