Hi Team, As previously mentioned, we reported the issue under Case ID: 7747625, and as part of the resolution, the Contact Notes entitlement was incorporated into the App ID. However, we then encountered an issue with the App ID prefix, which changed unexpectedly. While we've seen some progress such as the app update functioning with the new prefix. We’re still facing a critical issue with keychain access. Currently, keychain data is completely inaccessible, which is preventing seamless usage of the application. It seems that the prefix has successfully transitioned to the Team ID, but the stored data is no longer accessible through the new keychain access group, which is tied to the new App ID prefix. Additionally, we’ve observed that while the prefix has been updated for the main app target, the extension targets are still using the old prefix (5________A), and keychain access within those extensions remains non-functional. These blockers have had a severe impact, delaying our app release by three months, and we are struggling to address these issues and provide a smooth experience for our users. Thanks & Regards
