I've read from people who have been accepted this year, as well as in past threads, that on the day that they receive a decision, both acceptances or rejections, their checklist portal won't load in the morning and they receive a decision around 4pm that day. So far this year decisions have been sent out on Thursday afternoons.
And you will see a small purple button "admitted student portal" in the top right corner on your checklist page once a decision is ready for you to view. Seems that people are able to view their decisions by just checking their Albert page at random rather than receiving an official email right away. An email follows the posting of your decision later that same day.
