The new Deco app is a lot slower to initialize than the previous generation. It take 3-5 second after launch to be able to get into parental control.

Here're the steps:

1) kid misbehaves

2) parent launches Deco app

3) parent goes into Parental Controls tab

4) parent has to wait 3-5 seconds before blocking the internet for kid from step #1. 

Can you please try caching the previous session state on the device, so that at launch, while you are fetching new state, the user can interact with the app immediately.
