Note that i am using 3.9.149 for survey123 field application and 3.9.120 survey123 connect
This is expected. If you disconnect the internet, then your device is offline. The maps used for a basemap in Survey123 geopoint and other map questions are using online hosted basemaps in ArcGIS Online. Therefore if you device is offline a map will not be displayed.
If you want to use your device offline, you need to ensure you have loaded offline basemaps on your device, such as a tpk or other supported offline map packages. See documentation here: Prepare basemaps for offline use—Survey123 for ArcGIS | Documentation
In previous versions the map widget was displayed but the map was blank (grey) and could not be used. The basemap was still not loaded as you are offline, so from that point of view it is the same. The different now is we do not show the map as we can not use it without a basemap.
