iPhone won't ring while watching videos on Facebook (Finally a Solution!!!!)

So after going down the facebook and apple support rabbit hole I have finally figured out the easiest fix for this. Simply delete the facebook app all together and head to safari and bring up facebook from there. Then after you have been directed to facebook's website, click on the square with the upward facing arrow icon. Then scroll down and click "Add to Home Screen". Move this bookmark to the same spot on your homescreen where the facebook app used to be and.....Viola!! Bookmark is the same graphic as the app. Now when you are watching videos on facebook you will hear your phone ring! Your Welcome!
