Lost data

[MDecART]

Hello, ive been using draw.io for about 1 year. Works really well, however recently I made some updates to an existing file. I copied the diagrams and spaced them to the right of the existing diagrams. I then spent a while updating the copy versions. Very disappointed to have gone to the file today and found that the changes I made have not been saved. This is not only very frustrating it is also curious as from my understanding Draw.io auto saves everything?

Can anyone assist in retrieving the data? is there known bug in the app that might have caused this?

Thanks

What location were you saving the diagram to?

Google drive

If the save to Google Drive failed, you will have had a warning when closing the tab about unsaved changes. Are you certain you actually saved the copy to Google Drive?

Yes the file I was working on was already saved into google drive.
