The current expo upload:ios command does not have the same effect as the expo upload:android command. The Android command submits the new app binary for review and the update is available to users in the Google Play Store (once the review has finished). The iOS command only uploads the new app binary to TestFlight and then someone must manually create the new version and submit for review again in the App Store Connect console to have the update available for users in the App Store.
I know there might be technical limitations here in regards to Apple's workflow for submitting app updates to the App Store but is this something expo is working towards? As developers, It is a shame that we cannot currently automate the entire iOS update workflow the same way we can for Android updates.
