Excellent. Some of the UI updates optimistically, which is why certain places update immediately. Other parts of the UI are dependent on the return of the API call, which is why there can sometimes be a slight delay.

Hi TMyers ,

We tested this quickly again. It behaves as you describe now, which is along the lines of what we'd expect. The modal dialog shows null quickly and doesn't flip back anymore. It still seems a bit delayed in how it updates reported properties (some are changed by our software as a result of nulling that property out). The shadow panel seems to update faster in this respect, but the modal eventually shows the right content, and it's predictable according to our current testing. So I think this issue is fixed and we can close it.

Thanks for the quick turnaround!

teba99 - I did some digging into this, and found that AWS handles null values slightly differently than string values. I made a small update to how we display null values in the UI. What you should see now is when you update the config values on the Device Configuration modal it should update right away in the shadow display even if you're adding null values. The shadow display will not display {"property": null}- it will not display anything due to how AWS is handling null values.

Can you clear your cache completely and take a look at the updated displays? I think this will better meet your needs, but I'd love to get your input.

I was not able to replicate the scenario where the value changed initially and then changed back.

Let me know your thoughts when you're able.
