Using APM 10.7 SP3 and configured the domain.xml to sync domains to universes in Team Center.
After the configuration, when opening the Team Center and trying to create experience card for that universe, there are no attributes associated with that universe.
So experience cards cannot be used
In the SuperDomain universe, or any manual domain for that matter, it works fine.
Release : 10.5
Component : APM Agents
This is a limitation of the current product design with no workaround if the agent is in a custom domain.
