Hi， @Ryan.Paredez  Thank you very much for your reply. We have seen the description of this part of the document you mentioned, and we have no problem using it. You know, our project(React Native) is using AppD for performance tracking. According to the data collected online, the network request data collected by Android is about 4K. But IOS collects about 350 pieces of data. The number of sessions is 310 for Android and 420 for ios. We don't know why there is such a big gap. According to the test account we used to verify the discovery. During the same period, IOS collects data only for part of the time. Only network request data is not collected, but reportMetric data can be collected normally.  Looking forward to your prompt reply. Thank you very much. ^ Post edited by @Ryan.Paredez for formatting reasons ... View more
