indexeddb lost when updating app from cordova-android 9 to cordova-android 11

Hi,

We have an app that's currently on app/play store and uses cordova-android 9.
We created new version of the app with cordova-android 11 (to align with google requirements).
When we do the update from store version to new version, all storage data is lost.
Any idea what could be the problem?

We're using storage like this:
` IonicStorageModule.forRoot({
driverOrder: ['indexeddb', 'sqlite', 'websql']
}),
`
