That's what they are by now, though. The websites of social media sites are crippled and bug-ridden - try using Instagram in a browser, for example. They want to coerce you into using their apps, because that gives them better tracking opportunities.
Sometimes. YouTube (and Google Maps, and old.reddit.com but not default reddit) I find to be better on the website than the app.
That's just what I've been doing after deleting Instagram from my. phone. I can't trust my evening dopamine-seeking behaviour with the phone app, but there's much much less stickiness in the browser.
