someone help me please 
When I run ionic serve for the first time, the browser shows the app as styled in Android (md). Once i CTRL-S and reload, I get iOS style.
Not sure if that’s happening everywhere, but it might be happening to you.
As @jaydz inferred try:
ionic serve --platform=ios
ionic serve --platform=android
ionic serve --lab
Yes my problem is it. thanks for helping
