That’s just to make your own device. (Not needed) go ahead straight in your flow, go to WHEN device capabilities, choose the availability card.
No problem! Happy to help! 
Every time I try to add Leap S3 Pro Android TV I get taken back to the device selection screen after entering the pairing code.
Additional observations:
Scanning takes long
To rescan I have to open the Android TV App again. Adding doesn’t work a second time
Sometimes it doesn’t find my Leap S3 Pro at all
I cannot add my tv. I install the app on Homey, add the TV, het the paring code on my tv screen, enter it in the Homey app, and i get taken back to the add device screen, nothing happened. When trying again i can’t add the specific TV no more and need to delete the Android TV app from Homey and install again to retrospect. But with the exact same results.
Seems to be the same issue as @Bisch …
Edit: the device suddenly appeared. But with an error. When repairing it works, until i switch the device off, than is immediately unreachable again until I turn it back on again (using the normal remote) and repairing again…
