Not working in IE 'Object doesn't support property or method 'findIndex'

getIndex: function getIndex(id) { return this.stack.findIndex(function (loader) { return loader.id === id; });

Same thing here with IE11

A polyfill that should fix that problem

Something like babel-polyfill or the polyfill from Mozilla is probably your best bet - I don't think react-loader-advanced should provide this.
