NEW UPDATE — Jan 4, 4:40 PM PST After waiting 7 days, nothing has changed. Apple Developer Support is not responding to emails, and there has been no activity or response on this forum thread either. App Clips remain completely inactive. During this time: Reactivated several App Clip Experiences Updated multiple existing Experiences Waited additional time for propagation None of these actions had any effect. No updates, no reactivation, no new changes are reflected on devices. At this point, App Clips appear to be fully stalled on Apple’s backend, regardless of configuration changes made in App Store Connect. If anyone from Apple or the community has insight into recovering App Clips from this state, or knows of internal limits / reset mechanisms, any guidance would be greatly appreciated.

NEW UPDATE On December 29th at around 8:00 PM, I deactivated almost all App Clips, reducing the total from 1,341 to just 4 active App Clips. As of December 30th at 10:43 AM, there has been no change. App Clips remain completely inactive, and there are no visible signs of recovery or system response. At this point, it feels as though the system is not functioning as expected. We will wait a couple more days to see if there are any changes. Also we've submitted a ticket on Feedback Assistant on December 27th. Here is the ID FB21450030 - just in case Apple Development Team will see this post

We have similar problem. I'm posting updates here https://developer.apple.com/forums/thread/811196

Providing a quick update on our investigation. Today (from ~11:00 AM to ~8:00 PM), we manually deactivated ~500 App Clip Experiences and also made updates to a few others. This reduced the number of active App Clip Experiences from ~1,341 down to ~796. We’ll wait 24–48 hours to see whether Apple’s servers start propagating updates or responding to App Clip actions again. Hopefully App Clips haven’t entered a permanently “dead” state due to the previously high number of total App Clip Experiences. I’ll post another update once we have more data. If somebody had any similar experience or know more deails feel free to share.

After further investigation, it appears the issue may be related to the number of App Clips (1,300 app clips). When we had around ~750 App Clip Experiences, everything worked correctly (creation, updates, activation/deactivation). Once we added ~500 more App Clip Experiences, App Clips effectively stopped working. For the past 4 days, Apple appears to ignore all App Clip–related actions: Creating new Experiences Updating existing ones Deactivating or reactivating Experiences Nothing propagates to devices. A possible workaround might be deactivating ~500 App Clip Experiences and testing again. However, it’s unclear whether deactivated Experiences are still counted as active on Apple’s backend, in which case nothing would change. We’ve contacted Apple Developer Support and are waiting for guidance. Has anyone seen similar behavior with a large number of App Clip Experiences or knows of any hard limits or backend constraints?

We encountered a similar issue. The problem was that the App Clip size exceeded 15 MB, even though a 100mb allowed size was allowed. After adjusting the size of the App Clip, it functioned flawlessly.

App Clip Deactivated. You can see it here
