The Orion app on iOS can't open an app installed on my iPhone. It doesn't recognize I have it installed. In fact, when I click the link, instead of opening the app, I am transported to the App Store page of the app, where I can see "Open". This is an example with the TikTok app.
It should redirect me to the designed app, not to the app's page on App Store. Here’s an example with Safari
