iOS app breaks when chrome is installed

Currently running ionic v1 project on latest ionic cli version.

Alert() and onesignal does not work on iOS devices with chrome installed, when no chrome app is present on phone these functions works as expected.

Anyone experienced this behaviour before? I don’t even know where to start debugging this, as it’s something I’ve never come across before.

Would perhaps crosswalk solve this, as far as I understand that forces chrome, which is apparently what breaks these functions?
