How does the Translate Widget SiteData value relate to the URL subdomain in Step 1 and the "code" that helps me access the script HTML?

I created a translator widget using the tool here:

https://www.bing.com/widget/translator

I created it using the value https://test.example.com in Step 1 (note TEST subdomain).

I connected the widget to my outlook.com account and the free 2,000,000 word Translate subscription in the Azure marketplace. I can access the widget on the portal directly by going here:

https://www.bing.com/widget/translator?code=[mycode]

which I discovered by following the instructions in this blog post:

https://social.msdn.microsoft.com/Forums/en-US/e2e9ba65-ffb1-4e73-9300-fd54927f4f6d/widget-translate-associate-the-site-with-a-translator-not-working?forum=microsofttranslator

Note the post says the bug has been fixed, but I had to use it to create my first widget, and it only ever worked one time, I have not been able to create a custom widget using this method on any other subdomain of my original URL.

Now, while I am on https://test.example.com, I get the full functionality while logged in to the appropriate outlook account (including anonymous suggestions, Sign In, Dashboard, and Manage Suggestions).

BUT when I put the widget code on a different subdomain, https://dev.example.com, the following happens:

- translations that I have approved on test.example.com APPEAR CORRECTLY on dev.example.com

- NEITHER the widget Sign In feature, NOR the anonymous suggestions appear on dev.example.com

- when I try to create a new widget for https://www.example.com, it does not work (specifically, after I associate the widget to the Azure subscription, it throws me back to the widget page without a proper SiteData, and no way to obtain the code since it does not ever appear as described in the aforementioned blog post.)

Obviously my goal is to get a correctly working widget on www.example.com (anon suggestions and managed approval).

Since I can't create a widget for www.example.com now, I must assume that the test.example.com widget is somehow interfering. I tried multiple outlook.com accounts, multiple browsers, compatability mode, etc, but nothing I do can get the widget to work for https://www.example.com.

Can anyone tell me how the URL is associated with the SiteData, and how I can disassociate test.example.com if indeed this is part of the problem?

Thanks!
