Unsure how to get the download of the previous lesson on my app

I enjoyed the past two lessons a lot, but I'm struggling to download the information of the previous lesson on my android device as my device doesn't have the same email address on my computer. Is there a way that I can get that info on my computer or that I submit the email on my android device and ask them to set the info available on the other email- there is not much of a difference between the two email addresses.
