You may have noticed a new account named "Compte Lydia" was added to your account list in-app.
This account will now be credited by default when your friends send you money with Lydia.
No action is required from your part, and your usual experience should remain unchanged.

You can transfer the balance to another of your Lydia accounts or to your bank account. You can also send money to one of your contacts.
Add « Compte Lydia » as favorite in app
If you only or mainly use Lydia to send and receive money, I recommend you change the display order of your accounts in-app so this new account appears on top. You can do so from the "Preferences" screen.
