I have an app already published on App Store and by mistake, we configured it with a test Airship app for production. I created a live Airship app and it is working fine for new installs. However, it is not registering the device tokens for the users who are updating the app and had push notifications already enabled.
I tried UAirship.push().updateRegistration() and it is not working. I can't find anything else in the documentation.
This is Mikey with Airship Technical Support. Thank you for reaching out with your request. In order to assign the appropriate channels to the production app, you'll need to resubmit an update to the app store with the correct keys associated. This will allow the devices to register to the correct project.
