So we have deployed the IE mode within Edge, successfully to a group of pilot users.
In the main it is working very well, however on some websites, we have some very specific issues with certain elements on a page not working despite the page correctly launching in IE11 mode.
1. Collapsible element, that is used to expand a body of text does not work.
2. Buttons, for example a PDF button that will download a copy of a PDF does not work (I inspected the code and can see this is calling a OnClick() function).
Both points above work fine when we load the sites in IE11 independently of Edge.
Would anybody have any ideas as to why this is happening or some troubleshooting we can try?
