Checklist
Co-op not working
Fixed on 27 October 2026: rooms used to work only when one particular person hosted. The game now tries a server relay through either player, not only the host. A guest on a slow link is caught up instead of running minutes behind, and runs that were silently missing from the ranking since 26 October are accepted again. If your room still fails, the checks below are the next layer.
First checks: everyone must use pokesurvivor.com online with an account. A guest does not have the required friend/account features. The offline zip cannot join co-op. Invite by in-game nickname, not a third-party room link.
Reconnect rather than erase: verify a stable network, sign-in and current game version on both sides. The game tries peer-to-peer then account-backed relay. The 22 October patch allows guests to wait up to 45 seconds after a brief host disconnect. Do not clear all browser cookies or delete site storage to diagnose a room.
If a room freezes on cards: 25 October notes fix a lost card/item/Bond completion message that could stall everyone. The same patch redirects enemies away from disconnected teammates after three seconds. These are documented fixes, not proof that every current outage is resolved.
Progress differs across devices: save on the device that earned it, reconnect the other device and verify balances and ownership. The 25 October cloud fixes address stale writes, tickets and coins; the older description that coins simply follow the newest write is not reliable current guidance.
If errors persist, record both device/browser versions, host versus guest, approximate time and whether the disconnect occurred entering a rift or selecting a card. Report that context through the official project channels without posting account credentials.

Questions
Why did my invite do nothing?
The other person may be a guest, on a different domain, or in the offline file.
The boss one-shot us in a full room. Is that desync?
Maybe not. Boss HP rises with each extra player.
