Fix: Can’t invite a friend (Online co-op / Cross-play)

Quick fixes when invites fail: version mismatch, privacy settings, cross-play isolation tests, and network sanity checks.

Quick fixes

  • Same version on both sides
  • Online status is visible (not “offline/invisible”)
  • Privacy allows invites and cross-network play
  • Restart platform client + game

Cross-play isolation test

Try co-op with someone on the same platform.

  • Works there → cross-play pairing/settings issue
  • Fails there → general online/network issue

Network checks

  • Avoid strict Wi-Fi (hotel/school)
  • Try wired or stable 5GHz
