I've created two offline areas in my field map and would like to change the thumbnail. Is it possible?

How did you create the offline areas?  Through MMPKs or through creating offline map areas of a web map?

Hi Brynda, offline areas of a web map.

Are you seeing these thumbnails in your device in the Survey 123 app?  Or someplace else?

I don't think there's a way to update the thumbnail from the offline area manager interface. But I do have a hosted notebook that includes a step to update an offline area thumbnail. It updates with a public image I have in ArcGIS Online. Here's the relevant code if you want to give it a try: 

from arcgis.gis import GIS
from arcgis.mapping import WebMap
gis = GIS('home') #authenticate
webmap_id = '' #item id for webmap item
thumbnail_url = '' #url for thumbnail image
wm_item = gis.content.get(webmap_id) #access webmap item
webmap = WebMap(wm_item) #ingest as a webmap object
offline_area = webmap.offline_areas.list()[0] #specify offline area from list of offline areas for webmap
offline_area.update(thumbnail = thumbnail_url) #update offline area thumbnail
