Ask HN: Why has Slack / Spotify now stopped working in slightly older browsers?
In the last few weeks, Slack stopped working in Firefox 78, Yelp stopped showing maps and reviews in Safari 12 and Firefox 78, and Spotify can't even load a track in Safari 12. What changed to break these apps so fundamentally in relatively recent browsers (<4y old)? There are a lot of little things like https://caniuse.com/mdn-javascript_operators_logical_nullish... There is a belief among devs that browsers are being kept up to date well because of security fears but they aren't. OT: Spotify is apparently experiencing an outage in Europe [1] so I went to HN to check if it's not being discussed here. Found this thread but it seems it's not related, as here users are being forcefully logged out and unable to login again (hopefully not a hack) even in the latest Android app and up-to-date browsers. [1] https://twitter.com/search?q=spotify&src=typed_query&f=live Here's the thread discussing the spotify outage: https://news.ycombinator.com/item?id=30603574 FWIW, I’m using a macOS Safari that identifies as v6.something that Slack deprecated many months ago. I use the developer tools to have it identify as v9. Everything appears to work just fine. So IMO the only reason Slack isn’t working in older browsers is because they’re being capricious pricks.
