LinkedIn is garbage. I was trying to do some things on mobile. Nope. Gotta download the app. Switch to desktop mode, okay now you can do the thing.
I loathe companies that force their app by making an almost unusable mobile experience. If I didn't use LinkedIn to keep up with networks professionally, I wouldn't be using it.
It's far easier to control your experience, harvest your date, and feed you ads on an app.
Also keep in mind that on Android, apps will opt to use Webview, which Google has said they're injecting their web environment integrity bullshit into.
I'm an android developer, so I fully understand what you're saying which is why I absolutely refuse to use any app that I don't absolutely need. If it's simple enough, I'll just make my own app, haha.
