Cannot select page

Have had this issue from the start and it’s still not working. Whenever we click the blue button to login to facebook to select the page it does not work.

Yes, Facebook opens. Yes it asks for permission to see my pages. Then when I press okay it just sends me back to the wordpress instant articles app. Without allowing me to select the page? This happens to all our admins..

Please help, because many people are having similar issues it makes the entire app unusable.

If have tried different apps and have deleted permissions many times.
