App upgraded and now I have two integrations

My wife’s iPhone recently upgraded the app to the 2.0 version (is this also called 2019.1?).

I have mobile_app: enabled in my home assistant install. I also have ios: enabled which I was successfully using before, including with actionable notifications.

I now see two integrations for her phone. A mobile_app integration that has a lot of sensors etc, but ios has its own battery state and battery level sensor (only those two entities in the iOS integration).

Do I still need the iOS integration, or can I remove it? I’m unsure what might happen to the actionable notifications if I remove it.

Also - the ios battery sensors seem to update regularly whereas the mobile_app better sensors do not seem to… Might this be fixed by removing the iOS integration?
