Facing the same problems on Iphone mobiles
It works perfectly on pc;s and tablets (Ipad) however it still is not function properly on Iphones and some Android mobiles. It is an old issue (first questions over two years old) but appearently you cannot possibly resolve this mobile issue for the mainstream mobile phones, which is a pity.
Tried most solutions you provided in the past , but still fails to excute on a mobile phone
