Hello! I have completed Lab 1a. I have not completed Lab 1b but I was instructed to continue onto lab 2a. Once I got to lab 2a, I paid the $19.99 to download and access the app. Once that was done, and I was redirected to the app, it would not let me get on and the app would not show up. I have not been able to access Lab 2a and I am not sure where I went wrong or what the error is.
Please advise. Thanks!
