Gmail notifications incorrectly appear under WhatsApp

Gmail notifications are incorrectly displayed under WhatsApp in Niagara Launcher's notification previews.

The same Gmail notification also appears correctly under Gmail in Niagara Launcher.

When tapping the incorrectly displayed notification under WhatsApp, WhatsApp opens instead of Gmail.

Android's system notification panel correctly identifies the notification as coming from Gmail.

Expected behavior

Gmail notifications should only appear under Gmail in Niagara Launcher and should open Gmail when tapped.

Actual behavior

• Gmail notification content appears under WhatsApp.

• The notification also appears correctly under Gmail.

• Tapping the incorrectly displayed notification opens WhatsApp.

• Android's notification panel correctly associates the notification with Gmail.

• The issue only occurs in one direction. WhatsApp notifications do not appear under Gmail.
