I could build my react native app using expo build:ios and I have the .ipa file. I went to App Store Connect to upload my app. However, it is not showing an option to download the Application Loader. How can I get the Application Loader or upload without it?
Thanks

Application Loader is only available on MacOS. If you are using Windows or Linux, I recommend you installing a virtual machine (for example using VirtualBox). You can follow this link: https://techsprobe.com/macos-mojave/
After installing the virtual machine, you can easily install Application Loader there.
