Yo, I had this exact problem last week! Facebook saying session expired kept popping up no matter what I did.
What worked for me was resetting my password. Sounds weird, but it fixed it instantly. Go to the login page, click "Forgot Password," and follow the steps.
If that doesn’t work, maybe try using a VPN? Sometimes location-based glitches cause this.
