Hello everyone,

since the iOS/safari 11 update we have a problem with rising unique visitors on mobile iOS as well. We cannot use first party cookies / MCVID either, since we have to track data from multiple domains. If I understand your "Adobe Analytics and ITP" article correctly, then this problem shouldn't occur at all, since the third party cookies should've already been blocked by safari before. We're using omtrdc.net, too. It sounds like a quite similar scenario as mubarakd5726232's.​

The even bigger problem is, that these additional visits/sessions mess up our marketing channels data, since the "new" sessions are recognized as internal visits (HTTP-referrer comes from internal domain on session start).

Is there anything we can do to solve this problem?
