Hey @andsoff! I'm seeing the same exact problem with our app clip implementation. We thought maybe it had something to do with our web implementation in React of the smart app banner, but we're not sure. The example you've provided is reproducible for us on both web through the smart app banner and through iMessage links to the app clip. Through logging, we were able to determine that the app clip is receiving a URL in func scene(_ scene: UIScene, continue userActivity: NSUserActivity) but not the correct URL for that page. i.e. mysite.com/?txt=abc -- app clip receives mysite.com/?txt=abc mysite.com/?txt=def -- app clip receives mysite.com/?txt=def mysite.com/?txt=ghi -- app clip receives mysite.com/?txt=ghi mysite.com/?txt=jkl -- app clip receives mysite.com/?txt=jkl mysite.com/?txt=abc -- app clip receives mysite.com/?txt=jkl mysite.com/?txt=ghi -- app clip receives mysite.com/?txt=jkl It seems like there is a cache somewhere that recognizes a certain link is tied with the app clip, and knows to open that app clip, but always passes in the last used URL.

@otaliptus, what was the exact problem you had with React, causing the smart app banner not to display?
