I was transferring 3 different common Pokemons (my first transfers) and did not get any candy for it.
I picked one to Transfer, pressed Transfer button then Yes. Nothing happened, just the Yes/No dialog closed, I still saw the same Pokemon with Transfer ability in front of me.
Exiting Pokemon details view, particular Pokemon disappeared for good, I thought that it is supposed to work like that, but I got eventually no candy for that...
When and how are candies assigned to my account?
P.S. This happened 3 times as I tried.
