ID41 Endpoint disappears with Devolo Magic 2 Powerline but not Devolo DLAN

This is weird - just upgraded from Devolo DLAN 1200 mbps to Devolo Magic 2 Powerline.

With DLAN 1200 all is plug and play - Roon finds all endpoints.

With Magic 2 - my ID41 has vanished. All other endpoints still there!

Put back to DLAN 1200 and the ID41 re-appears…

Any ideas?
