[AC Question]

I have a strange situation in that I have horrible internet, but unlimited mobile data on my phone.

I want to cast to my chromecast without using WiFi data when streaming something on my phone (Note 4). Unfortunately, since I must be connected to WiFi to connect to my Chromecast, the phone defaults to using WiFi data instead of mobile data.

I have tried using firewall apps, but for some reason if I block the WiFi access of apps it won't instead use mobile, it will just not be able to access anything.

Any suggestions would be appreciated.
