For this symptom, the most relevant fix is to verify that Phone Link is allowed to show message notifications and badges in the app, then refresh notification permissions between the PC and the phone.
- In Phone Link on the PC, go to Settings > Features > Messages.
- Turn on Show notification banners.
- Turn on Badge on taskbar.
- In Phone Link on the PC, go to Settings > Features > Notifications.
- Confirm notifications are enabled.
- If needed, select View apps and make sure the messaging app is not disabled.
- Reset notification syncing on the Android device.
- Open Settings on the phone.
- Search for Notification access.
- Find Link to Windows, turn it Off, then On again.
- Select Allow when prompted.
- On the PC, open Phone Link > Notifications and wait for notifications to refresh.
- Check Windows conditions that suppress Phone Link notifications.
- Make sure Battery saver is Off on the PC and phone.
- Make sure Focus assist is Off on Windows.
- Make sure Do not disturb is Off on the Android device.
- On the Android device, disable battery optimization for Link to Windows, because it can interrupt notification delivery.
- Settings > Apps & notifications > App info > Link to Windows > Advanced > Battery > Manage Battery Usage > Battery optimization
- Set Link to Windows to Don't optimize
- On some devices: Settings > Apps > Link to Windows > Battery > Optimize battery usage > All > Link to Windows > Off
- If the badge still appears only after opening Phone Link, reset the Windows app:
- Search for Phone Link from the taskbar.
- Right-click it and select App settings.
- Scroll down and select Reset.
- Restart the PC, open Phone Link, and reconnect the device.
If notifications appear inside Phone Link but the taskbar badge updates only after opening the app, that usually points to notification sync or badge state not refreshing until the app session is active. The steps above target the supported notification, badge, permission, and background-delivery settings that affect that behavior.
