Cannot update hosted feature service

Unable to edit on my hosted feature, my edits won't take.  ESRI performance page is up and running.

Use the browsers dev tools or Fiddler to monitor the edit request and check the response for the error, or look at the Server logs and see what's going on.

What is Fiddler?  AND, Can you give a screen shot of the Dev Tools, and, how does one access Server Logs?

The dev tools also do that, but record traffic on the page you're using. Press F12 and you'll see the developer tools come up:

Select the Network tab and then make your edit and you'll see the request getting sent:

Then, inspect the response to see why it failed, (yours will likely have an error):
