We're experiencing this also... same issue. Players are beginning to write in asking why starting a multiplayer match crashes immediately. Have you had any progress towards resolution on your end, or is this (I assume) just an issue on Apple's end?

And we also are using "inviteOnly"... which is required for the game setup we have. We've had successful real-time multiplayer going for awhile now, and just experiencing this in iOS 16.4 and higher. Would love to know if anyone else is experiencing this too...

Same here. Can't submit. Anyone else having this issue?

I get this error when I look at the inspector in the browser... logLevel : "ERROR" message: "API Response Error: POST_REVIEW_SUBMISSION_ITEM_RESPONSE" stackTrace: status code: 409 --- api correlation key: XXXXXXXXXXX And this... "errors" : [ { "id" : "83553362-8832-4205-a45d-ecb87ffc25db", "status" : "403", "code" : "FORBIDDEN_ERROR", "title" : "The given operation is not allowed", "detail" : "The resource 'reviewSubmissionItems' does not allow 'GET_COLLECTION'. Allowed operations are: CREATE, UPDATE, DELETE" } ] }
