Links open App Store instead of installed app. When is Apple going to fix this?

Every time I encounter this issue I can’t believe it’s still happening. While browsing on safari I inevitably come across a website that’s “way better in our app!”. Usually mobile centric companies like Pinterest, Instagram and Reddit.

After being harassed by pop ups enough times I finally download the app, and click on the obnoxious “open in app” button when the opportunity presents itself again. However that’s not even what happens. Instead I’m brought to the Apple store download page, for the app in question...which I already have on my phone...K.

Because I'm a sucker for punishment I then click the “OPEN” button within the Apple Store, which simply brings me to that app’s home screen. At this point I can’t even remember what I was trying to get to anymore.

Why hasn’t Apple fixed this? I want to play by the rules and experience things the way developers intended, but for some reason that’s way easier said than done.
