I tried to have a look onto the TDF dashboard at https://dashboard.documentfoundation.org using an Internet Explorer 11, but with no success. The website didn’t render. I got only a retry of rendering actions. According to the browser stats at least 5.26 % of the internet user are not able to view the site (https://www.stetic.com/de/market-share/browser/).
And in addition for those who prefer webservices with ‚mobile first‘ implementation: it’s not for you ;-(
The site doesn’t render proper on smaller mobile devices. It’s not usable on such devices.
