Notice flags Facebook in‑app browser issue that intermittently drops cookies

A website notice has warned of a specific issue affecting Facebook’s in‑app browser, saying it intermittently sends requests to websites without previously set cookies. According to the notice, this behavior can occur when links are opened inside Facebook rather than in a device’s default browser.

The notice says the problem appears to be a defect in the in‑app browser and indicates it should be addressed soon. It does not specify a timeline for a fix or how widely the issue has been observed. As a temporary workaround, users are advised to continue using the Facebook app but avoid the in‑app browser by opening links in an external browser instead.

This approach is presented as the simplest way to steer clear of the problem while a resolution is pending. The issue is described as intermittent, meaning it may not affect every session or site visit. Until the underlying defect is resolved, websites accessed through Facebook’s in‑app browser may occasionally behave as if no cookies are present, prompting repeated logins or consent checks.
