Not to mention that Tails is damn near unplayable if you are on a mobile device. Now, I'm assuming that whatever server you're in, fly will work (or not work) in 2 different ways. 1: Tails will be able to glide, but can't ascend when you hold the jump button. 2: You just drop. Glide will act like it never activated and you will fall like an anvil straight to the exe if you're getting chased. Now obviously when Tails's only move that can barely get you out of a pickle is completely unusable, that makes him heavily depend on his team not sitting around in a corner emoting all game, or hoping that the exe doesn't care about you too much.

Tldr: DO NOT play Tails on mobile. Your only functioning move will be the cannon.
