[MPPM] Lobby Not Found When Using Quickjoin

I just updated to 6000.0.2f1 from 2021.3.8f1. When using multiplayer play mode, I host a game. When I try to quickjoin that game (also in MPPM) it throws the following exception:

No lobbies available via quick join: Unity.Services.Lobbies.LobbyServiceException: failed to find any open lobbies matching the search criteria —> Unity.Services.Lobbies.Http.HttpException1[Unity.Services.Lobbies.Models.ErrorStatus]: (404) HTTP/1.1 404 Not Found at Unity.Services.Lobbies.Http.ResponseHandler.HandleAsyncResponse (Unity.Services.Lobbies.Http.HttpClientResponse response, System.Collections.Generic.Dictionary2[TKey,TValue] statusCodeToTypeMap) [0x0006d] in .\Library\PackageCache\com.unity.services.lobby\Runtime\Http\ResponseHandler.cs:122

This happens on the joining client whether I’m hosting from player1 or player2. When trying with ParrelSync, there is no error, and everything works just fine. I should also note that the hosted game appears in a list of available games and I am able to connect to it directly. This is only an issue when using the quickjoin call LobbyService.Instance.QuickJoinLobbyAsync(). The Lobby version is 1.2.0, the MPPM version is 1.0.0
Updating any deprecated code did not effect the error.

Updating to MPPM version 1.1.0 did not help this issue.

The minimum editor version for MPPM 1.1.0 is 6000.0.3f1, just confirming that you also updated the editor version as well as the MPPM package?

I did not. I will look into that and report back.
