Playfab matchmaking error

Can anyone tell me why this is not working? I’ve read the error messages but can’t figure out what to fix.
LogPlayFab: Response : {“code”:400,“status”:“BadRequest”,“error”:“MatchmakingAttributeInvalid”,“errorCode”:2046,“errorMessage”:“There were no latency measurements found for any of the users in the ticket. Since the queue has thunderhead enabled, latency values are required to be sent for the region selection rule.”}
LogBlueprintUserMessages: [PlayFabGameInstance_C_20] There were no latency measurements found for any of the users in the ticket. Since the queue has thunderhead enabled, latency values are required to be sent for the region selection rule.



Did you come to any conclusion?! I have the same issue!
