I changed my policy to MirrorAllSnapshots. Why is my snapshot not replicating?

Answer

Manually create a new snapshot on the source volume and run an update. This new snapshot will then replicate, as will all new snapshots going forward.

Additional Information

A recent snapmirror policy change from MirrorLatest to MirrorAllSnapshots did not replicate a manual snapshot that was created before the policy change.
Snapmirror policy changes of this type will only replicate snapshots that are newer than the latest snapmirror snapshot.
Between the time that the manual snapshot was created and the time the policy was assigned, a snapmirror update was triggered; causing the manual snapshot to be older than the latest snapmirror snapshot.
