• Import this seed into the RN app, or create a new wallet and generated activity for different address types.
• Run the native app to trigger migration and make sure all activities pass correctly.

Note

The RN app doesn't back up on-chain activities on the remote backup, which means if user recovers using mnemonic and RN backup activities from unsupported address types won't show up.
