Is there any way to have your own tile service as the default basemap?

[PeterTimmers]

I've been trying to find a way to change the basemap in a survey to my own tile service or AGOL webmap, or even use your organisations basemap gallery.

There's nothing in the Connect app from what I can see.  

I've been dabbling unsuccessfully in the .info file with no luck?

Hi Peter,

This can be done through editing the .info file after initial publishing and then republish - refer to Include a map in your survey—Survey123 for ArcGIS | ArcGIS  for more information
