Microsoft Forms allows you to quickly create surveys with various question types, including choice fields. There may be times, where the number of choices is very large (for example, US states). Based on some initial assessment on the Choice field, there is a limitation of 60 options that can get stored for a response. However, you can exceed the number of options in your survey and all that Forms will do is display a courteous warning message at the top of the page.
Now, if you were to fill-in the survey and select an option that is greater than 60, all those responses get pooled into the "Other" option.
This behaviour occurs regardless of Single or Multiple answers, or Ordered or Shuffled options.
We experience the same issue when combining several multiple choice/drop down lists. The limitation popups when we're nearing a certain limit. It seems that the calculation is done on the full size of the survey including titles, subtitles, choice lists and even branching options. Quite inconvenient when you want to use MS Forms as the source for a simple input process.
What's the size limit and is there a way to extend the limit?
