I hit this last week… but now I’m pretty sure code is getting rolled back / work is being lost.
Support: please look at my “txtops-a” notebook.
The last section had 4 lines an hour ago. I downloaded a zip to save to github (I can provide that zip for comparison, if necessary). Now it’s back to one line - like it was before I started working on it a couple hours ago. Two other sections are also in their previous state.
Appreciate the help and investigation.
