I am using 1.0.71 on KitKat.
Immediately after voting, the arrow is displayed in red and the vote count is correct. However, when I scroll to read answers and then back to the top, the arrow is grey again and the vote count is reset to the previous value.
A reload of the question (pulling the finger down) is needed to show the correct situation, which is kept from then on.
This case was on security.stackexchange.com but I observed the same behavior on other sites too.
- original state:
- scrolled down and back up
- after a reload
