It's incredibly annoying and troublesome how everything AutoSaves when you navigating from one section to another in D365.

Whether you're editing an email, page, form, customer journey etc, as soon as you click on the left hand menu the system automatically autosaves the on screen content, without warning. Sometimes a user may have tested a small update and had no intention to save the progress, or perhaps two people are incidentally editing the same content and one autosave overwrites anothers data without warning.

A simple popup saying 'would you like to save your changes before leaving this page' would make a massive difference.
