It used to be that you could click a link in an app, it opens in your web browser where you're already logged in to the relevant service, so you get to see the content the link points to.
These days, you click a link in an app, it opens in an in-app web view where you're not logged in, so you just see a login screen.
Not even the "open in Safari" button works, since by the time you have the opportunity to click it, you've already been redirected to the login page. You literally have to long-press on the link, copy it, switch to your browser, and paste it in to the omni-bar. I don't understand how this god forsaken industry's UX "experts" have all agreed that this should be the universal user experience.
It's especially bad in apps like Slack, where 99% of the links I'm ever interested in are links to our internal gitlab, some internal knowledge base article, some internal tool, or some other thing that requires being logged in to view any of the content. Links just plain do not work almost ever in Slack without the manual long-press -> copy -> switch to Safari -> paste dance.
