@premacck Thank you for notice, I already reacted there.

@JasonAHeron For the last months we weren’t face with this issue again, nevertheless as I see from the comments above and also duplicating issues such as #1808, probably the bug is still exist. By start of the year we are planing several campaigns which will use the IAM, and the campaigns will be on the big audience, based on those data I will be able to tell you if this bug is still actual for me or not.

Thank you in advance see you next year.

Merry Christmas & Happy New Year to all 🎊.
