How to upgrade cordova-plugin-ionic-webview without data loss

Hi there,

I’m trying to upgrade cordova-plugin-ionic-webview 2.5.0 to cordova-plugin-ionic-webview 3.0.0 (or higher)

I followed the migration guide on npm: cordova-plugin-ionic-webview - npm
As well on their plugin’s github website GitHub - ionic-team/cordova-plugin-ionic-webview: Web View plugin for Cordova, specialized for Ionic apps. without success.

Whenever I upgrade and run the app on android I loose Local storage.

I’m using ionic 3 and cordova-android 8

Any ideas why and how to resolve this?
