What I have:

I have a flutter app and I am using the unilink plugin to forward deeplinks. On Android, everthing works as intended, but not on iOS.

This is my iOS json:

http://connector.horizonpedia.com/.well-known/apple-app-site-association

and these are my XCode .entitlement Settings:

I also checked my URL params in Info.plist:

Json passed the test on https://branch.io/resources/aasa-validator/

I am pretty sure I have done everything correctly except ticking this box

Problem:

as you can see, the target runner checkbox is unticked and I can't tick it by clicking on it.

any ideas how to solve this?
