I Got RT working after re-pairing the pad with Android in X-input mode (as opposed to what the instruction leaflet tells). You need to remove the existing 8bitdo pairing in Android, then start SN30 pro+ by holding X and start, then press pair button for 3 sec. After that you can create a new pairing in Android and RT should work in Minecraft. Hopefully this helps.
