Activation code took hours to show up

Just wanted to let someone know that it literally took 2 hours for my activation codes to show up in email.  I also tried logging into my Roku account during device activation and it also sent an email..  2 hours later.  In the meantime for anyone else having this issue, my workaround was to login using the alternative method by using a QR code and typing in the last 5 digits of one of my other devices.
