Sogou browser can not receive the files and URLs sent by the fly. How to do

Sogou browser's flying function is very convenient, users can use the fly transmission function to directly connect the computer to the mobile phone. However, in the course of use, there are often files/URLs that cannot be sent by flying, so what should I do?
In fact, this is very simple. For iPhone: Go to the phone “Settings”, click “notify”, enter the notification center, find “search dog browser”, open the four options in the picture. If you do not receive the notification in time after opening the notification center, it may be caused by the delay of Apple's push service. Please be patient.
