Users reporting Secure Storage contents deleted after updating to encryptedSharedPreferences: true on 9.2.4

[i5hi]

Two users of our wallet application reported that their app deleted contents of secure storage after upgrading to our latest version where we used encryptedSharedPreferences: true

One user was on a Samsung Galaxy 24FE and the other was on a Pixel 8.

Is there a known issue with 9.2.4 where migration is occassionally unsucessful? Is there anything we need to do to manually migrate?

Is it safe to update to 10.0.0-beta ?

This is quite concerning for us because if a user has not backed up their wallet their funds will be permanently lost due to this issue; we relied on the integrity of secure storage to protect these secrets.

Additionally, we have never used the resetOnError setting or ever had any code that manually deletes the contents of the storage. All users have their secure storage contents intact since the release of our application around 3 years ago.

Also noticed that I am no more able to run older versions of the app that use encryptedSharedPreferences: false, to test migration - even after deleting the latest app. Is this expected behaviour?

[i5hi]

I see you have a PR open for this.

Note that this is happening on modern devices while the PR seems to be concerned with older Android versions. Hope that adds useful context.

Also, will there be an issue migrating my users from 9.2.4 to 10?

[i5hi]

Is there anyway I can recover this data? I cannot revert back to encryptedSharedPreferences: false anymore and there seems to be known issues with mixed mode usage as well.

Any help on this will be hugely appreciated.

More context: We did not set allowBakcup:false in AndroidManifest.xml

@i5hi Your customers are likely seeing a java.security.InvalidKeyException: Failed error. Please review the README again. As you mentioned, it’s crucial to disable Auto Backup (android:allowBackup) in your AndroidManifest.xml. That should resolve the issue.
