Thanks for your answer. I have been interested when I saw you manage to work on IE9 in ionic, because I know that very few people will work on this in 2016...
I have to make an app for IOS, Android, Windows 8.0 and Windows 8.1.
I was told that windows 8.0 was base on IE9, so I wanted to test on it, but it seems to be wrong (https://blogs.windows.com/buildingapps/2012/11/08/internet-explorer-10-brings-html5-to-windows-phone-8-in-a-big-way/).
So I will focus on Windows Phone simulator and debug in IE10 is needed.
Thanks again for your help and your advices
