[Bug]: Notifications not received for second imported wallet

**Describe the bug**

Users are unable to receive notifications for the second imported wallet. Notifications work as expected for the first imported wallet, but no notifications are triggered or delivered for any subsequent imported wallets.

**Expected behavior**

Notifications should be received for all imported wallets, including the second wallet.

No source file or test is identified. Reproduce the issue using the listed steps with two imported wallets on version 13.19.0, then trace the notification handling for subsequent wallets. Done means notifications are triggered and delivered for the second and later imported wallets, with regression coverage added if the existing test structure supports it.
