Never an option to cast

Hi,

I have an iphone 6, running ios 10.0.2, and an Amazon Fire TV.

I’m playing video content stored on a NAS. The video plays fine via in the (paid for) Infuse app, but there is never a button to allow me to cast when I’m watching the video. I’ve tried .mp4 and .avi files, with the same results.

Is there anything I can do?

Thanks in advance.

Casting to a Fire TV is not supported at this time. Sorry.
