A customer withdraws marketing consent at 10:14 in the morning.
The consent system saves the change. CRM receives it and updates the customer record. Somewhere on the way back, however, the acknowledgement disappears.
Thirty seconds later, the sender tries again.
The customer has made one decision. Yet a poorly designed consent history can now show two withdrawals simply because the same message travelled twice.
That may sound like a small technical oddity. It becomes much more serious when Privacy, Compliance or Legal later relies on that history to understand what the person actually did.
