Notice cites Facebook in-app browser issue dropping cookies; workaround urges external browser

A public notice warns that Facebook’s in-app browser is intermittently making requests to websites without cookies that had already been set, potentially disrupting normal site functionality. According to the notice, the behavior appears to be a defect in the in-app browser and is expected to be addressed soon.

Until then, the suggested workaround is to continue using the Facebook app but avoid opening links within its embedded browser. The guidance recommends launching links in a standard mobile browser instead, a step intended to ensure previously set cookies are recognized and sites perform as expected.

No timeline was provided for a permanent fix. The advice is framed as a temporary measure until the underlying issue with the in-app browser is resolved.
