The CU 3.0 inbox doesn't show the list name for the tasks the notifications are about. This has caused confusion and discontent among our users within less than 1 day of switching to CU 3.0. The list in which a task is located puts a frame of reference to the task title. Right now a user has to open each notification to find out what list the task is in. This gets in the way of notification 'triage' making it more complicated to assess what to deal with first. Please make the list name visible for each notification or at least make it an option to turn this on in the inbox settings. Soon, please!
Update: just had the first roll-backs to CU v. 2 among our users due this issue.
