Hi Charudatta,

Is it possible that you were using this app for many updates with different keys and now you reached 10kb limit? You can try to clear all data first by something like following:

var request = null; for (var key in yourdata[viewerid]){ request = opensocial.newDataRequest(); request.add(request.newUpdatePersonAppDataRequest("VIEWER",key, ""),"status"); request.send(status); }
