[2020] Controller Bug?!!

Hey, I have noticed when I use my PS4 controller with my iPad, the right and left joystick buttons don’t work like when you click down on them. Also The touch pad on the PS4 controller also doesn’t work. If you could fix this, please ! It will make me happy and probably many other people. ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️🙏🙏🙏

I bought the controller just so I could play fortnite mobile with it bc I don’t have enough money to buy a whole console and a tv❤️❤️❤️
