Why can’t I use spells while riding dragons

I got the Dragonborn dlc and I can mount dragons and all, but I can't use my destruction spells (lightning bolt, sparks, flames or anything) while riding a dragon. How can I use spells while riding a dragon?

Best Answer

You are able to use your spells and shouts while riding a dragon, but only once you've ordered the dragon to start attacking a target. Once you're airborne, your dragon can scan for nearby enemies (the Help menu should give you the keys for your particular platform, I think it's triangle to lock on, L3 to attack).

Once your dragon has engaged an enemy, you should be able to use your shouts and spells to assist.
