Hello,
Here are a few reasons why this might be happening:
Windows Version: Swift Pair is available starting from Windows 10 version 1803. If your Windows version is older, you won't see this feature. You can check your Windows version by going to Settings > System > About
Bluetooth Adapter: Not all Bluetooth adapters support Swift Pair. If you're using an external Bluetooth dongle, it might not have this feature. You can check the specifications of your Bluetooth adapter to see if it supports Swift Pair.
Best Regards,
Hania Lian
