Currently, with the new Admin Console, there is NO INTUITIVE TOOL to send a user another e-mail when they say they have not received the first e-mail that Adobe supposedly sent. Ever since we moved to the new Admin Console on the experience cloud, it seems a lot of your e-mails are captured and sent to a user's Junk/Spam folders, which makes it a lot harder to manage new users to the system. I don't have an interface where I can say, "send this person another e-mail" like we did specifically within Adobe Analytics.
Something you should have at least considered was maintaining parity when migrating to your new system. Honestly, we really don't need anything more to undermine our organization's trust in Adobe Analytics.
