App getting stuck after migrating to new Apple device

We have an app running nicely using Angular & Ionic - we’ve noticed that when we transfer the App to a new device when setting up, it refuses to move past the initial splashscreen. We think it may be either something related to ionic or sqlite.

Has anyone seen anything similar? It’s obviously clearing somesort of cache or local storage?

I’d start off by connecting the app to the browser and attaching the dev tools. If you can connect it, reload from the devtools to see if any errors are getting thrown.

It’s most likely sqlite issue if you are migrating to a new device as apple doesn’t do a full file transfer unless you do encrypted backups.
