I don't know whats happening but at the moment I have a current rate of about 100% fail rate for catching pokemon for the new version of 1.5.7.1, also the map is not working with the new version. I am not sure if this has anything to do with the catch rate.
Went back to version 1.4 to check if I could catch pokemon, still says it is failing all the time. Am I doing something incorrect?
