we made a little app which works great on ios, android and all browser but, when using IE11 on Windows 7, we are not able to click on anything, it’s like there is an invisible layer on top that block all interactions.
I inspected your code in IE11 on Win 7 and found that Ionic was placing a<div class="click-block"></div>within the <ion-app> ... </ion-app>and that’s what is blocking everything.
Check this old thread, it should be still relevant for this problem though.
