Let's say I published a survey from survey123 Connect and after a few days people have already entered data into the survey.
If I want to change the word of a question, not its field_name just the label, and I publish the survey again will it affect the pre-existing data that has already been entered?
This may be a silly question, but I just want to be sure.
That shouldn't cause any issues, I believe only changing the structure of the data (field names, field types, adding repeats) is where you would be required to overwrite the existing data. I'd recommend taking a copy of the data anyway just to be sure though of course. And FYI when you click publish when you're republishing an existing survey and you've made changes that require an overwrite it'll warn you and tell you that you could lose data. You can see a full list of what can and can't be changed here: https://doc.arcgis.com/en/survey123/browser/create-surveys/updatesurvey.htm
