I recently started learning Ionic and so far it looks great. I have just one issue that I can’t solve. When I build app for Android the tabs are not showing. It is in my private app and also in app from lynda.com course about Ionic: http://www.lynda.com/AngularJS-tutorials/Working-tabs/368920/386111-4.html
In browsers preview they are just fine.
There is a placeholder for them but they are invisible.
Here is codepen with html code: http://codepen.io/anon/pen/pJVmRY
Any suggestions how to fix that?
