I have been trying for about two weeks to get Universal links to work in my app VineCrawl. For some reason it always tells me that it cannot parse the association file. However, other tools for testing the association file have no problem. I didn’t sign it since I am targeting iOS 11 and later. A long time ago, I read somewhere that it could be the https cipher that I use, but now I can’t find anything on that. My file is vinecrawl.com/.well-known/apple-app-site-association
