I have issue uploading my Survey123 data. I created an earlier version the form and used it to test some data. When I downloaded the data as shapefile, the name of the file was "surveyPoint". I later had to refine the form, so I deleted the data from the "Data" tab of the Survey123 website. When designing the new form, I may have changed "surveyPoint" to "TourismPoint", I can't remember how and now I am getting an error. The screenshots are attached. I had try the suggestions on Troubleshoot—Survey123 for ArcGIS _ Documentation but it did not work.
The failed uploads
If you renamed the layer name, you probably did so at the Item Details page of the layer:
You should be able to rename it there to allow submission to continue.
I was showing the Item Details page in your ArcGIS account for the feature layer that the form uses- you should be able to find it in 'My Content'.
