Great feedback, @Sean_Aquino. I use estimated and actual times fields as well and they are super helpful.
You should still be able to multi-select tasks in your My Tasks list to get the aggregate values in fields on the right- you can see a screenshot of My Tasks for today below.
Can you try this again and/or send a screenshot of what you’re seeing when you do this?
You could also do this in search reports for tasks across projects, and I use this often to see my estimated time for tasks due on future dates.
