Thread:Talk:Compatibility/Who doesn't use JavaScript and Why?/reply (2)

That header is intended to list: the reasons why a user would get the no-JavaScript version of the site, whilst using a browser that does support javascript.

Mobile users apparently get this fairly often? The gov.uk link mentions it ("network errors, especially on mobile devices"), and I was told this directly by a WMF mobile dev.

Feel free to edit for clarity :)
