Issue with events from mobile SDK in iOS newest versions

Hi,
Has anyone experienced issues with mobile SDK events on iOS version >26.2?
We are facing cases where events reach AEP for devices with version 26.2 or older, but not for newer versions in the same use case

Hi,

 

Yes, we are seeing dataset ingestion errors from those Safari versions due to multiple ECIDs. Those are coming from webview links which are tagged with an app ECID url parameter to be inherited, but WebSDK for some reason is sending both that and the native webview cookie ECID causing the error.

This is probably related to iOS’s Private Relay which WebSDK likely needs to be updated for, this is the logic we have implemented as a workaround for the bug in our tag manager:using the onBeforeEventSend functionality to modify the payload before the calls are sent. 

 

1. Checks for ECID in the event payload (content.xdm.identityMap.ECID).

2. Extracts and decodes the ECID from the query parameter (adobe_mc / MCMID).

3. Prioritizes the query parameter ECID if present; otherwise, it falls back to the first ECID.

4. Marks the remaining ECID as primary (let me know if you wish to skip this step)

5. Removes any duplicate or temporary ECIDs generated by Safari.
