Lobby Attributes Not Persisting to Dev Portal (OSSv2 + Lyra)

Description:

I configured Lyra to use OSSv2 for startup. Login works correctly, but the lobby I create cannot be discovered by other players.

I can see the created lobby in the Dev Portal, but it does not contain any of the attributes I specified.

If I check the Dev Portal immediately after creating the lobby, the expected attributes appear for a short moment, but they disappear after a few seconds.

I also tested updating the lobby attributes a few seconds after creation. The Dev Portal still does not reflect any changes.

However, when I query the lobby through the EOS Lobby Search API, I can find the lobby and see all the expected attributes there.

It seems like the lobby attribute data only exists locally and is not being properly synchronized or persisted to the EOS backend?

Test Environment:

•   Operating System: macOS

•   Unreal Engine Version: 5.6.1 (Source Build)

•   EOS SDK Version: 1.17.0
