Hello,
At the beginning, I must apologize for my delaying.
These days, our teammates are checking the mailbox and sending emails with education code. As far as I can see, you will receive an e-mail in reply these last few day. And if you still have some problems about edu discount, you could refer to https://forum.marginnote.com/t/60-off-upgrade-code-for-marginnote-3-application-guide/242/5.
Please inform us about the results!
Sincerely,
Bryan
