company is now selling this exact functionality as an SDK

Is the "Open Parent App" functionality included – without using a local push notification?
For them it’s easy to distribute private API because they don’t have to deal with app review or are risking their developer account from being banned.
This is the feedback I have received from Apple:
There is private API to do this (and it works)
But you will have your developer account banned when app review discovers this.
There are apps on the store using this private API for many years – without consequences.
I would recommend to wait until there’s an official API (maybe next month at WWDC??)
