I downloaded part 3 for android and it won't advance the story. I then tried to go on the game discord to ask for help and the captcha verification won't work and I can't get on there. Extremely frustrated.
What is the exact issue you're having? As an alternative, you can always start a new game in chapter 3, which will start you right where chapter 3 begins (and then rename your character in the options).
I'm not sure about the discord verification, as it's a 3rd party bot, though people still seem to be joining.
