Please do not submit support requests or "How to" questions here. Instead, please use one of these channels: https://forum.ionicframework.com/ or http://ionicworldwide.herokuapp.com/

Current behavior: very long startup time (90!!!! seconds) after first installation of the app (android&ios). after this long process, the app works normally. this just appears after first install or update of the app.

Expected behavior: 2-3 seconds startup time.

Steps to reproduce: Using latest ionic 3.9.2

What command did you use to build your app? From where are you installing the app - stores? beta distribution service? What kind of devices are you testing with?

Hello! Thank you for opening an issue with us! Would you be able to provide a sample application via GitHub that demonstrates the issue you are having? Thanks for using Ionic!

[sansan88]

I'm using Ionic Pro to build the app as production apps via App Store and Google Play Store. tested on iPhone 8 IOS 11 and Samsung Galaxy A3 Android. The Repo is private, I can give you read Access if you provide me your github username.
