Ios back button issue

app page will move back twice (instead of going back to the previous page it will go back to two pages back) when ios back button is clicked once.

are your state-urls are correct?
i mentioned this, when you have a duplicated / in your routes --> this happend for me when i define a parent state and a child:

url-parent; '/base/'
url-child: ‘/child1’

right:
url-parent; '/base/'
url-child: ‘child1’

state urls are correct. This issue was not there before ionic upgrade. This issue is appearing after ionic upgrade
