I can confirm this works.

Are you sure you have the volume activated _exclusively_ on the single
node.
'is used on one node' doesn't mean much when any other node is allowed
to activate the volume at any time.

When the LV is exclusively activated (lvchange -aey) snapshots should
work (and they do work for me).
