Flying Troubles

Hello Mojang! I am here to say that I do not know 100% that this is a bug, only that it seems to have just started when i tried this new snapshot. So anyway I bet you are wondering what my problem is? Well it is just that when flying i am usually able to just sprint instantly while in the air, but wiht this most recent snapshot I can't? Well that's a lie, I can I just have to start of sprinting on the ground. So Yeah, I have no idea, as before said, if this is a bug but in my eyes (and knowledge of bugs) it is. If you have read this, thank you! And I hope that if this is a bug it can be fixed A.S.A.P! Goodbye for now Mojang and I may be here again soon!
