Unintuitive Inbox behavior
New tasks are automatically categorized into the Inbox. The Inbox doesn't synchronize across devices and requires manual assignment into Google task lists before synchronization. The old behavior is to only show Inbox items in the Inbox. Now all Google tasks show up although they are synchronized. This breaks the workflow of making new tasks in various task lists and then going to the Inbox to assign them into categories that makes sense so that they can be synchronized. Now, you need to immediately assign them right after each task to make sure synchronization happens, which is tedious and slows down your input of tasks to remember. This reduces the utility of Endeavor being a easy to-do app that I can use to quickly jot down tasks and come back to them later, as I need to think about the category and due dates for each and every task instead of just typing them in and worry about them later. If I miss any of these I had to dig around and look for any that says Inbox, which requires scrolling through a lot of tasks which is not only tedious but also can't even make sure that I didn't leave any unassigned. If I need to see all my categorized tasks at once, I'd rather go into the All category.
