Check the shared-session baseline before deeper fixes
Co-op Baseline
Keep multiplayer simple enough to trust before the session starts.
Use this when the problem is invite flow, version drift, ownership, or lag.
This helper keeps the shared-session checks in one place so the next page can be gameplay, not troubleshooting.
Baseline checks
Start with the shared session, then move to the exact co-op page.
NeedBest fitWhy
Invite flow
Check the shared world joins first
Use this when the room exists but the session still feels split.
Version match
Confirm the patch baseline
Use this when the world loads but the version still feels off.
Save ownership
Clarify who owns the main world
Use this when the backup path or host role still feels unclear.
Latency
Check whether delay is the real issue
Use this when the session works but play still feels noisy or slow.
Co-op shelf links
Use these when the baseline needs a second page.
