Capacitor 4 Migration Storage issue (Android) - new version not retrieving values stored by old version

We’ve migrated from Ionic 5 / Capacitor 3 to Ionic 6 / Capacitor 4.

The app uses the capacitor/storage plugin that was re-named capacitor/preferences in Capacitor 4.

When I do an upgrade test on a couple of Android devices that have the old Capacitor 3 version installed, any calls to storage are returning null values instead of the values that were saved using the old version of the plugin - has anyone seen this issue when migrating from 3 to 4 ?

All iOS devices seem to work ok.
