Dont bother, the fix is just a few lines of text and the only guy to get it working is paying for two dynos $25 each per month. There was supposed to be updated deployment videos but that was weeks ago. There is no support in the slack group with lots of students giving up. Here is a direct quote from a student a few days ago "I am actually thinking about ditching the course entirely, so far it was a waste of time.". Thing is you can get your money back if your unhappy but students are to scared to ask because the last person that called him out got banned from slack and publicly shamed with pictures of their comments posted to twitter even though the slack is supposed to be a safe private group for students to interact. My advice is to go to one of the bigger online course sites which are much cheaper and they have teaching assistants that answer questions really quickly. I think Wesbos likes the idea of being a teacher but cant be bothered to help students and doesnt handle criticism professionally.
