Unsupported browsers and OS

To focus on delivering the best possible experience in Slack, it is necessary to keep the list of supported browsers and operating systems short.

When a browser is no longer supported, we stop fixing pesky bugs and issues. For a customer, that could be a terrible Slack experience! We do our best to avoid that scenario by blocking unsupported browsers from accessing Slack.
