Hello,
After releasing my App to close testing on Play console, in pre-launch report, I received the performance issue on screen initialize.
Issue : Runtime error : Attemp to invoke interface method ‘java.util.Iteratorjava.util.List.iterator()’ on null object reference.

This app is working fine on some devices.

What I have tried to resolve this : Checked or Unchecked show Lists As Json

Are you using web component to get a response ? Maybe a delay in getting response from web causing the error so check if list is empty or not before run a procedure or check list’s lenght

Please provide more information such as used components and extensions.
