feedback

Logging on o On shape this morning there is no sign of the model i created yesterday. It appears that I have lost a whole days work. This is the first time this has happened to me in a ac few years of using On shape. Can I request a back up copy?

I reach the end of the tutorial and the feedback window pops up asking for feedback. The only option at the end is "End Tutorial" which exits the tutorial. The "next" arrow does not work.
