The curveball is a tactic in Pokémon GO that many players have had trouble mastering, but there are many who have perfected the art of the curveball so that they can consistently get the extra experience. Sadly a new glitch is keeping those talented trainers from receiving the experience they deserve.
Apparently when trainers catch a Pokémon using a successful curveball they are not always getting the experience. This has personally happened to me so I can confirm that the glitch does indeed exist. We can only hope that Niantic fixes this glitch as soon as possible.
