I had 2 separate apps, 1 for iPhone, 1 for iPad (not my idea, I wanted Universal from the beginning). I've already converted the iPhone to a Universal app so I don't need any help with that.
Now I'm wondering, do I remove pre-existing iPad app from sale in iTunesConnect. (I know how to do this as well) or is there another way that would allow users with iPad app downloaded to be alerted that a new, Universal app exists to download.
The way it is now, if I just remove iPad app from sale, they won't be able to redownload it, but they won't necessarily know there's a Universal version unless they look at list of apps by us or search for app by name.
I see that others have asked the same thing years ago and wonder if an update has changed anything: Merging existing iPhone and iPad app ids into a single universal app id
Thank you for your time.
Put out a final update on your existing apps, that puts up an alert explaining that there's now a universal app, and just leave your existing apps on the App Store.
