No - the bug is earlier, where a user on an old browser is directed to a link on meta.discourse.org that doesn’t work on an old browser. The user with an old browser should be directed to a page that has no minimum browser requirements.
If the link for “switch to a supported browser” is helpful or not is a different question and not part of this bug.
Yeah just confirming what @moin has demonstrated: as with any Discourse topic, the recent browser-support announcement is available to view in any browser. There will be an ‘unsupported browser’ banner at the top, but the content should still be there.
@pnorman if your community member is unable to read the content, please could you ask them for a screenshot, and precise browser version, so we can investigate?
