That’s not true. I run into the issue all the time. For example if I click a link in the peloton Reddit to a ride it opens up in the browser, and not the Peloton app.

If I click a link to a tweet it opens, at best, to safari which then asks “do I want to open it in my twitter app”. At worst it just opens in safari without giving me an option.

Reddit links work similarly. And there are plenty of other examples. Meanwhile on android you can easily set default apps and to borrow a phrase, it just works.
