What's interesting is I have another iOS that uses App Clips as well but on a different domain. The App Clip settings look pretty much the same on both apps and AASA is fine on both domains as well. However, it works perfectly fine on the other app. When the URL has an App Clip associated, it shows an App Clip popup. If it does not have it, it shows default Safari notification. But on this app, it just keeps showing the CPSErrorDomain error 2 when the URL does not have App Clips associated with it or it has but it's been temporary deactivated.

One more use case of unexpected behavior with a new URL: /baz /baz does have an App Clip associated within App Store Connect and works fine, as expected. But whenever someone deactivates it within App Store Connect, it starts showing the same CPSErrorDomain error 2.

I'm going to add more details here: I've clicked "Clear Experience Cache" countless times. Here's what Settings -> Developer -> App Clips Testing -> Diagnostics show for two URLs that are on the same domain but with different path (a.k.a /foo /bar at the example in the original post): This is diagnostics data of the URL that does have an App Clip associated: https://short.com/foo This is diagnostics data of the URL that does not have an App Clip associated: https://short.com/bar (Note: same domain, slightly different path)

@Arxos have you had any issues with Apple creating placeholder experiences? This seems to be a good workaround but still I wonder what would Apple do if they detected this behavior.

Any updates @Madiska ?

Any updates @natebrierhinge?

I had the same issue and spent lots of time figuring it out. Here's what currently works for me: // data field data.relationships.localizations.data.0.id = 'EN' data.relationships.localizations.data.0.type = 'appClipAdvancedExperienceLocalizations' // included field included.0.id = 'EN' included.0.type = 'appClipAdvancedExperienceLocalizations' included.0.attributes.title = String included.0.attributes.subtitle = String included.0.attributes.language = EN
