I was able to connect my Logitech MX vertical in earlier versions. However, in the latest version 20.2, I can no longer bluetooth connect my MX verticle. It keeps notifying me "make sure MX vertical is turned on and in range". (P.S. I can connect other bluetooth devices such as my earbuds). I am using thinkpad x1 tablet which comes with Intel Bluetooth
