Secure Storage doesn't keep items when switching to unimodule


I’m migrating my app’s code from managed Expo to a standalone RN app. In the RN version, I’m accessing Secure Store via the unimodule.

I’m observing that devices that have items stored using the former (Expo) version can’t access the items anymore after upgrading to the bare app. Am I missing anything?

Thanks a lot for your help.
