Microsoft today released a new update for Microsoft To-Do app in Apple App Store. This Version 1.62 update brings task assignment support. With this support, you can assign tasks to your colleagues, friends, family and others. To assign a task, tap on the detail view of a task in a shared list and then select the option to assign it to someone who is in that list.
This update also fixes an issue that removed formatting from HTML formatted notes if you edited something else within the task, like adding a due date or checking it off.
