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

[vladansaracpv]

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'] }),

I suspect you app is using a different "driver" after that upgrade. This looks like a pitfall that needs to be documented.

@vladansaracpv The issue is probably a combination of your driver order and an issue with indexeddb detection in local forage.

You can read a bit more about it here: localForage/localForage#999

I would change your driver order to sqlite first
