IIRC the Android OS requires the app to define which URL handlers it should be able to intercepts at compile time as a security measure so that an app can’t decide to intercepts URL it shouldn’t after being installed without your knowledge or consent.

The nature of the Fediverse makes it difficult to achieve that without hardcoding and maintaining a list of instances URLs in the app.

It’s definitely better in third-party reddit apps though.

I wish it would strip all the url parameters crap that are in Amazon URLs.

At least Cinny is kinda close UI-wise to Discord.
