I am also finding the same.
from what we have learned from people unpacking the code in the app they have made the odds of catching pokemon greatly lower
a green circle now means you have a 35% chance to get it.
then it goes down to 30% for yellow
28% for orange
and 25% for red.
I personally think this is a bug in the code, those were supposed to be individual values for some pokemon and got applied to all, leading to us going though more balls, and pokemon running more often.
I dont mind the 3 step bug being worked on, there are some nice rumours of what they are doing and it looks good.
I dont mind that pokevision is closed down, when the new nearby list comes into effect we wont need it.
what I do mind is the catch rate change. it has completely changed the state of the game.
google has already disabled refunding, and I see apple will follow suit.
for me, I am giving the guys at Niantic a week to fix this issue, or Communicate time lines about it to us (somehow communicating feels less hopeful than a fix...)
if there is nothing by next week wednesday and catch rate is still messed up I will uninstall and try again in a few months maybe.
