Using the AppStudio Map Viewer 4.2 template, I notice that the offline map areas don't display with the same symbology as the web map, and the layer names don't honour the webmap either.
e.g. this is the actual web map symbology
whereas the offline map area seems to default to the feature service symbology:
Can anyone else confirm if this is the case, and/or is there a way to make the offline map use the same symbology as the web map?
Tina Jin and I tested this, it looks like we are able to reproduce the issue using this webmap (7fa70e3e030143e4a112ba4e3ce003c2) with offline map areas.
