DevApp not showing on mobile on Ionic4 ( works on Ionic3 )

Hello, if I create blank app on Ionic 3, run ionic serve -c and run DevApp app on iPhone, I automatically can select app ( automatically detected on network ). But if I create Ionic 4 and run ionic serve -c, that running app ( web server ) is not detected automatically on network. If I type adress manually Im able to connect, it is working properly. But it is annoying to write IP address everytime :frowning:
