Rejected app: IPv6 network issue

First versions of my app were published with no problem, but since i’ve installed ionic cloud for notifications and deploy in my app, apple store rejected it twice.

I don’t really know what to do, any help would be apreciated.

What is the rejection reason you got from Apple?

Performance - 2.1

We discovered one or more bugs in your app when reviewed on iPad and iPhone running iOS 10.2.1 on Wi-Fi connected to an IPv6 network.

Specifically, the app content still couldn’t load properly after we logged in the app.

— Never happened to us in previous builds without ionic cloud

Hi guys,

I got the same thing. First version was fine, and then the second one was rejected for the same reason. It seems the app does not load. It just displays a white page (after the splash).
