Hi Ismael, Thanks for the quick reply. I have installed the ArcPro plug-in and have looked at the data in ArcPro and all of the polylines that I have captured with the app on my phone have the same error message {"error":{"code":400,"details":["'features' parameter is invalid","An item with the same key has already been added."],"message":"Cannot perform operation. Invalid operation parameters."}} although I am not sure what this error means particularly or how to prevent it from happening when I go out and test the app I built by collecting additional data. I have sent the qcr file to the e-mail address you put in your reply. I appreciate any help you and your team can give me in getting my QuickCapture app to sync. Thanks, Cathy Walker GIS Manager City of Maple Valley
