Visitors can’t post on my community Facebook page

Anyone else see this problem? URGENT! I have reported this for the THIRD time to FB, as have other Pages' Admin. My followers cannot post on my Community Page. They cannot see the space to post that usually says "Write something........"
This is true of every Community Page I have looked at; the Admin can view it, but no one else.
It appears that some can post from an iPad or iPhone, but no other way.
Is this Facebook's way of manipulating people to use Apple products?
THIS IS A SERIOUS PROBLEM...IT HAS BEEN GOING ON FOR OVER TWO WEEKS! Most Admins do not notice it; they just think their visitors are not posting as much.
