Sony a6000 can not transfer photos and video to IPhone 6S

Dear all,

I need your advice. I cannot transfer photos and videos from my Sony 6000 to my IPhone 6s after I upgrade IOS of my IPhone to ver. 11. Before, I can transfer photos and videos to my IPhone 6 successfully.

Need your advice whether IOS 11 makes photos and videos can not be transferred or not? Or maybe I need to change setting in my Sony a6000 or in MTB Sony a6000 .


Regards,
