My Launch is paired but isn't recognised
The Launch mus not be paired for this to work - this sounds counterintuitive
but you just need to turn it on (blue light will flash)
and click on "Connect Launch Directly" (or the other way around, doesn't matter)
and wait a few seconds (blue light on permanently)
