Thanks for reaching out in the community. The auto-save feature best functions when you have a good internet connection and will save every few seconds. You can also manually save your work by selecting file in the top left corner and save from the drop down options. If you have good internet connection and the auto-save feature is not functioning correctly, then that could be a document specific issue. If you believe that there is a document specific issue, please fill out this form and include the document URL, steps to reproduce the issue, and screenshots if applicable.
