[CA] Navionics Platinum+ maps shared between Axiom displays?

[tgades]

I have all 3 of my Axiom 12" displays at v3.2.101. I have only a Navionics platinum+ chip in the data master. All are networked via ethernet connection. All other networked assets are visible to all 3 of the Axioms (CP470, CP200, Evo AP, HD Digital radar etc).

The behavior/availability of the Navionics+ charts on the 2 non-data master displays is not at all predictable. Sometimes available, sometimes not with no apparent pattern to the availability.

Any suggestions would be very greatly appreciated. This was not at all a problem when my systems was networked A125/A125/A128 MFDs. Kind of regretting the upgrade at this point.
