Since this happened on both of your Laptop Studio PCs at the same time...
That strongly suggests the cause is not the PCs. The common factor is your Pixel Fold running Android 17 (or a recent update to Google Messages/Link to Windows). If the problem began immediately after updating, it may be a compatibility bug.
Try these steps in order:
- Force Phone Link to re-sync messages
On your Windows PC: >Open Phone Link. >Go to Settings > Features > Messages.
Turn Messages off, wait 30 seconds, then turn it back on.
Restart Phone Link.
- Check permissions on your Pixel
On your Pixel: > Settings > Apps > Link to Windows > Permissions
Make sure it has:
SMS
Notifications
Contacts (recommended)
Also go to:
Settings > Apps > Link to Windows > Battery
Set to Unrestricted.
- Reconnect Phone Link
If messages still don't sync:
On the phone:
Open Link to Windows.
Unlink your PC.
On Windows:
Open Phone Link.
Remove your phone.
Restart both devices.
Pair them again.
- Clear the message cache
On the Pixel:
Settings > Apps > Link to Windows > Storage & cache
Tap Clear cache (not Clear Storage yet).
Restart the phone.
- Update everything
Check for updates to:
Windows
Phone Link (Microsoft Store)
Link to Windows (phone)
Google Messages
Google Play System Update
- Test with another SMS app
Temporarily make another SMS app (such as Microsoft SMS Organizer, if available in your region) the default.
If Phone Link begins showing messages, the issue is likely specific to Google Messages after the Android 17 update.
Switch Google Messages back afterward.
- Reset Phone Link (Windows)
Go to:
Settings > Apps > Installed Apps > Phone Link > Advanced options
Click Repair.
If that doesn't help, click Reset.
