Cast to a nearby device pop up on HTC 10 (7.0)

A

AC Question

This pop up refuses to go away. whether am connected to wifi or just mobile data. Making me want to throw the phone against the wall.

I often have to restart the phone to make it usuable. The thing can't be dismissed, just keeps asking me to connect to a Chromecast device. I do not have a Chromecast and how would it even connect when wifi is not on.

I'm not sure how to post links to screenshots. Spam filter blocks it. One pop up says "Cast to a nearby device: Your microphone will be use momentarily to identify a nearby device". This one can be skipped. The second one can not be skipped, "Cast to a nearby device: Enter 4 digit pin...."
