You might notice that in iodé, apps can’t usually open their own links, for example, try opening F-Droid Link and you’ll go to the browser with no option to open F-Droid, even if it is meant to work right away.
This is because link verification is broken on AOSP and doesn’t work.
You can workaround this by adding the links yourself, either by going into an app’s info page and then in Open by default, or by going into Settings → Default apps → Open links.
Don’t grant more than necessary, some may not be verifiable or even useful, only grant domains you know belong to the same app, or when the app is meant to be able to open these links.
Fun app: Geo Share helps you get rid of those stupid app-specific links and just open them in whatever app you want.
It is also useful to have YouTube links open in NewPipe.
