Lobby imposes some limits on the parameters you can provide when creating a lobby:
- Players in a lobby: 100
- Lobby data values: 20
- Player data values: 10
Additionally, rate limits apply when making calls to the lobby service. Exceeding these limits will result in a 429 - Too Many Requests error which can be verified by catching the LobbyServiceException or by reviewing the Unity logs.
For more information, see the documentation on Lobby rate limits.
