Is Mesa2 a Windows 10 tablet? If so, please try another browser. Enketo doesn’t support Internet Explorer anymore: see “Farewell Internet Explorer” on https://blog.enketo.org/. Firefox or Chrome would be best, but if you’re not able to install anything new, Edge should work and is included with Windows 10 by default: https://enke.to/modern-browsers.
When attempting to use Internet Explorer, if you’re stuck at a loading screen and not redirected to the more-informative “Modern Browsers” page, then that sounds like a bug.
