We are finding that the New User Experience (UX) Roadmaps are very slow and can take up to a minute to show on Internet Explorer (IE) 11.
Chrome/Edge/Firefox work well and display within 3-5 sec.
Internet Explorer (IE) 11
The Roadmap slow performance is due to using IE11, this browser is unsupported for use with New UX. We have known performance issues with IE11 and this is why we do not recommend using it with New UX.
Users should use a different supported browser instead.
