Q: My facebook app says "cleaning". it has been like that for almost a week now, how do i stop it?

Hey Rey,

That is interesting that your Facebook app says its cleaning. I am not sure if you tried this, but try deleting the app and downloading it again from the App Store. Take a look at the steps below to take care of deleting the app.

Remove an app using the steps below:

1. Tap and hold on the app until it jiggles.
2. Tap the  in the upper-left corner to delete.

You might be asked to confirm that you want to delete the app. If you see a pop-up that says, "Deleting [app name] will also delete all of its data," tap Delete.   

Take care
