I have an Ionic3 app that has been in production mode in the store for almost a year. An update from
cordova-plugin-ionic-webview to version 2.3.1 and
UseScheme="true" improves the performance enormously! However, the whole storage is deleted. This is really fatal for an app in production mode.
What can I do to keep or transfer the data in the storage?
What I tried
I tried with plugin
cordova-plugin-ionic-migrate-localstorage but does not work, maybe because my cordova-plugin-ionic-webview version is too new for this plugin.
