First, I need to check if Reflex still requires activation codes for their courses. Sometimes, online platforms move away from activation codes to direct email confirmations or account-based access. But maybe for some users, especially if they purchased a group or bulk license, activation codes are still used. However, since the user is asking about 2021, which is a few years back, maybe the system is outdated or they need an activation code for an older purchase.
