If you are here, you probably already know the issue.
When you pair your devices with an operating system (OS), a unique "link key" is generated and stored on both the devices and the OS. The catch is that both Windows and Linux see your laptop's internal Bluetooth adapter as the same hardware, and thus, the same MAC address. When you switch OSes and reconnect, the new OS generates a different link key, which overwrites the previous one on your devices. This invalidates the pairing for the other OS, forcing you to "forget" and re-pair.
