I want to keep on changing the user email ID....

[Taran_Bhagat]

I want to keep on changing the user email ID. But only one ID will be authorized to access my app. at any one time. Can this work? Because I had previously put my email ID as authorized user under the monthly Pro Plan. My email ID is bhagat.taran@gmail.com. Then I removed my Id and added my daughters email ID. But she cant access my app. Kindly resolve this at the earliest please
