The root cause for the issue is after VC Activation the encryption key changes. This happens due to multiple installs and uninstalls, and the previous install’s encryption key is still saved in the keychain and used for encrypting data for the next install. After activating the VC new encryption key is generated. On reloading this new encryption key is used to decrypt the data due to the change in the encryption key the decryption of data fails. We have retested this in sprints 9,10,11,12, this scenario was not handled. The react native key store library has a method that prevents the app from generating the new encryption key for the new install setResetOnAppUninstallTo(false). This method is specific to iOS only.

The issue is not with logout or internet connection, we have tested the various scenarios and narrowed it down to VC activation.
