ArcGIS Collector: Why the collector is not able to access a web map?

Despite the fact that a web map is created successfully, the collector fails to access it

What could be the issue here?

Good point, thanks for the correction Kylie Donia‌!

I added your layer to a new map and saved it, and I see that map in Collector. 

Did you make your layer editable after you had made the map? If so, try resaving the map. There is some metadata stored with the map that doesn't get written if the map isn't editable, and that would explain a few of the things you are seeing here.

Good Catch Kylie. Precisely. This is what I have done. The editing feature is enabled after adding the layer to the web map viewer. It appears that enabling it afterwards doesn’t resolve the issue. However, saving the web map viewer resolves the issue! It works like a charm

By the way, I couldn’t figure out where the offline option is

As Katherine mentioned about, you don't have sync enabled on your layer. As a result, you won't be able to use it offline. 

The sync setting is a bit below the Editing one that you showed in an earlier screenshot.
