I needed to update my existing survey to help clarify some of the data I had been receiving. Before I published the survey again, I had completed the backup/export of existing data as suggested. Once the new survey had been published, the name of my hosted feature layer had changed. I imported the existing data back into the new(-ish) survey and thought everything had worked as expected.
But, now I have two hosted feature layers in the same survey folder in ArcGIS Online. When I look at the Survey123 site, it only shows the data for the new HFL. When I look at the old HFL in AGOL, I can see that data is still being submitted to it.
How did I end up with a new HFL with a new name? How can I turn off the ability to submit to the old HFL without turning off the ability to submit to the updated survey?
