RE-ENABLE WHATSAPP NOTIFICATION

If WhatsApp notification is disabled or improperly configured on your device, voice and video calls might not ring, even when your phone is unlocked. To fix this, inspect the app’s notification settings and check that WhatsApp is set to receive notifications. If everything looks fine, you can turn off WhatsApp notifications and re-enable it. That can help restore WhatsApp’s text and call notifications back to normalcy.
Step 1: Long-press the Gb WhatsApp 2023 icon and tap App info to reveal the application details page.
Step 2: Select Notifications.
Step 3: Toggle off the Show notifications option and toggle it back on.
