Hi, About SimpleLoader, I just extended Jewel SimpleLoader in my App framework, check if the browser is IE and disable it only showing a waiting ... message.
About the huge performance issue as mentioned in another thread, the issue is related with the way that js files are loaded in IE11 (IE11 is loading file by file and took a whole minute to load everything). So the release mode that it's a single file fix this problem and release mode should be the way to go anyway (I was using debug mode because issues detected in release mode). About the issues detected in release mode was fixed with the Harbs suggestion: -js-dynamic-access-unknown-members=true After all this, I found many other small visual issues related with IE11 that forced me to hack here and there only because of IE11. I removed IE11 support (Office 2016 perpetual for Windows) on my second upload attempt, however MS rejected it because they tested Office 365 (SaaS license) with an older version that depends on IE11 without update, so I was forced to support IE11 !! Third upload and let's see ... My future Royal Applications (outside of stores) I will officially don't support IE11. IE11 force as to put patch everywhere and the code became ugly for a portion of users that is more and more irrelevant.
