Practical check

How to verify your group before buying

  1. Compare platform editions.Open the store listing for every player in the group.
  2. Check the invite interface.Look for a publisher account, cross-network friend code, or platform-only invite option.
  3. Use official support for the final answer.If the platforms differ, ask Nacon support to confirm that exact pairing.
