Can’t post photos in FB iOS. No setting for it

My wife’s iPhone XR has the FB app on it. It will not allow photos to be posted. When you try it says it needs to have access, and takes you to the Facebook settings panel. There is no setting there for photos. There is Siri, notifications, background app refresh and cellular data. Nothing else. On my iPhone there is a page of settings, including photos. I have force quit the app, updated the app, no luck. Suggestions?
