Add AutoSave as the other office apps have
Word, PowerPoint, Excel, OneNote all have AutoSave. A feature that is a life saver and that it is easy to get used to.
In Visio this is not implemented for some reason.
I have had a Visio document that I have worked on for 2 weeks, on a Windows restart, it was all gone. Last save, 2 weeks ago.
The apps are all in the same family, I only save to Teams/Onedrive, I guess that right or wrong, I expected an AutoSave behaviour.
