Watch Providers - they open to website instead of installed app

When clicking either TMDB, Just Watch, or Reelgood, it opens their respective websites using Moviebase’s built in browser even though I have these apps installed. Ideally clicking either of those will open the app itself.

Device: Samsung galaxy z flip 4 (but problem existed on other android phones and app versions too)
Moviebase App version: 3.6.6
