We have the same issue. Were you able to solve it?

Turns out the issue was just a delay. The Advanced App Clip Experience started working a few days after I set it up.

I found that it doesn’t work because the parent bundle ID of the App Clip is already fixed when applying for it.

I’ve encountered the same issue. I’ve already checked the Advanced App Clip Experience and the AASA file, but I currently lack the means to further troubleshoot where the problem lies.

In the Diagnostics section of the Settings app, the NFC domain shows a warning: “The URL does not match the associated domains for this App Clip.” However, I have verified that my AASA configuration is correct, and the cached AASA file on https://app-site-association.cdn-apple.com/ is also correct.

My App Clip is only about 5MB in size.

When I visit nfc.ttwifi.net in Safari, the App Clip banner at the top does not appear. Instead, it shows the default App Store download banner. However, when I visit qr.ttwifi.net, the App Clip banner is displayed correctly. I checked the AASA configuration on app-site-association.cdn-apple.com, and the configurations for both domains are identical. Additionally, in App Store Connect, both domains are configured for the Advanced App Clip Experience.

I am using this method to configure the Wi-Fi: open func apply(_ configuration: NEHotspotConfiguration, completionHandler: (((any Error)?) -> Void)? = nil). However, in actual usage, regardless of whether the connection succeeds or fails, the Error is always nil, which makes it impossible to determine whether the specified Wi-Fi has been successfully connected.
