In my case the new api key doesn't help, seems the cursors are broken on the service side.

I'm experiencing the same issue with analytics endpoints Request: curl --location 'https://api.appstoreconnect.apple.com/v1/analyticsReportRequests/XXXXX/reports?cursor=AQ&limit=1' \ --header 'Authorization: XXXX' Response { "errors": [ { "id": "a171d897-14cb-40c9-b7a5-9fd35807d752", "status": "400", "code": "PARAMETER_ERROR.INVALID", "title": "A parameter has an invalid value", "detail": "'AQ' is not a valid cursor for this request", "source": { "parameter": "cursor" } } ] }
