Can anyone help with Facebook?

[HopscotchBanana]

Yesterday, my FB declared "your session has expired" which is something it's never done before. Then the screen went white.

Now each time I try to reopen the app, (Android phone) it briefly does the white screen, maybe 2-3 seconds, then closes.

I've updated the app on Google play. I've cleared cache. Restarted about 20 times.

Any ideas why this happened? Any ideas how to access again?

Thank you.

Have you cleared the data as well as the cache? If so, uninstall and reinstall the app.

Fuck me. That's worked.

I'm a bear of very little brain...

Glad it helped. It's the software version of 'switch it off and on again'.
