Hi @KayleeSC or @Pushpak-Ambadkar123 Are you saying that using this sample https://developer.apple.com/documentation/networkextension/filtering-traffic-by-url We just need to uninstall and reinstall the app everytime we want to do the testing? I still can't make this sample app to work. The example.com is still not blocked. Based on the log in the pir server, the pir server already being called.

@Pushpak-Ambadkar123 I didn't see any error at all from the app, im just curious, is there anything we need to do to make the sample application works
