What may be happening

The usable pathway includes more than hardware. It may depend on a particular command structure, application screen, background service, software licence, integration or account relationship. An update can replace or relocate one of those transitions without physically removing the product.

What the evidence does—and does not—prove

A change beginning immediately after an update or migration is relevant timing evidence, but it is not proof by itself. Compare the previous route, current route and any documented service changes before assigning a cause.

Examine the pathway

  1. 1
    Name what changed for the person

    Record the former command or action and the human result it produced.

  2. 2
    Separate presence from availability

    The feature may still exist while requiring a different route that is not functionally available.

  3. 3
    Check service and regional changes

    Confirm whether an integration, skill, licence or supported function has changed or closed.

  4. 4
    Document the restored route

    If a new pathway works, record it so the outcome does not remain dependent on one person’s memory.

Evidence boundary

Not every failure following an update was caused by that update. Coincidental outages, account changes, hardware faults and altered settings must also be considered.
