Actually I don’t know what you mean. I cannot find app-push-provider in the portal. I added app-push-provider in the two entitlements files. The problem can be there. Can you point me to the right section of the dev portal? Thanks!

Thank you very much for your response. I'm still encountering the same issue and would like to ensure that I'm not making any mistakes. I have set the Network Extensions in the Apple Developer Identity section. Then I found these two configuration files for the Entitlements: App-ios.entitlements Extension-ios.entitlements I added the following lines to both files: <key>com.apple.developer.networking.networkextension</key> <array> <string>app-push-provider</string> </array> Then, I cleaned the project (Product -> Clean) and archived it (Product -> Archive). The build succeeds as shown in the screenshot below: When I click on "Distribute", I encounter the same two errors again. I'm at a loss to understand what's wrong.
