Freezing pokeball.

Nope but that really stinks.

Yes, but it’s happened before the update too. You just lifted your finger off the screen enough that the games thinks you let go.

Yep. Seems to be more of a network connectivity issue within the game than an actual problem with the pokeball throw,

Used to happen to me relatively often few weeks ago, but in my case ball stuck, then I could pick it up and throw again.
