I'm used to working with ChatGPT's canvas function which auto-saves as you are working, but I got the student 1-year free offer for Gemini so I've been trying it out. Typically ChatGPT will periodically save your work even if you're manually revising something in a canvas and these will also be available to go back to as versions.
After three hours of manual revision within Gemini's canvas frame, I asked Gemini to take my updated draft and key the presentation handout to my updated script .
I see the sync icon working at the top-left suddenly and Gemini tells me it can't see any changes from the previous version.
My jaw dropped. Indeed, when I reviewed the text, every last thing was undone to the point where it was when I first began working on it this morning, three hours ago. Nor did my iterations come up in any of the previous revisions I could cycle back to. I could have screamed.
Fortunately redoing it all the second time around wasn't too bad (still took over an hour), but this time I did it inside a word processor.
To me this is a fairly serious reliability issue when it comes to doing anything serious inside Gemini's canvas. In some sense I was quite lucky to learn the lesson on something relatively minor (still a huge hassle).
