MS Forms is failing to save changes and new form information
I was having the same issue, but I think I've solved it for now. I went back to edit my missing questions, then copied the "edited" question, then added it as a duplicate question. I shared the Form in our Team channel and sure enough both the "edited" and "duplicate" questions appeared on the Form. I went back to Form, and deleted the "edited" question, which should be above the "duplicate". Shared the link again and my Form is now corrected. I've only tried it with one form but hope this solves the problem for now. Hope this helps.
It can result because of changing the values in the original table Forms creates. The best option I have found is to create a new tab, copy the original table to the new one (using =TABLE1 or copied version of each cell) and allow people to update the copied sheet as they like leaving the original sheet unchanged.
If you hide the original sheet and only show the copied one, you (and users) can do what you like with the new sheet (change column names, add columns at the end etc) leaving the original unchanged (useful for audit too)
