I'm sorry, but your browser is not supported in IE11 with Vaadin 8

When entering my new intranet with Vaadin 8 in IE11. I receive a “I’m sorry, but your browser is not supported” warning. We can click the “Continue without updating” link I’m pretty sure our users will complain about that.

Is there a way to get rid of the warning? thanks

We have this message only on an intranet. Is there a way to add the header to tell IE the minimum version it support (IE11)?

Late reply but in case it is of use to anyone, the easiest option to configure header tags is probably the add-on

. Alternatively, a bootstrap listener can be used directly, but requires considerably more lines of code.
