Developer mode activation code not working

Hmmm all mine is doing is spinning its wheels. Any word on a fix for this?

I have tons of similar scripting errors and failed requests, interestingly different ones depending on the browser, and the page is painfully slow. Unfortunately, I had no success in retrying so far. Do you recall the ball park of "n" in your case - is it dozens or hundreds of times?

Same. This has been a frustrating process from the moment it began. Microsoft needs to get more QA and development support on the portal used by software developers.

On Firefox:

The POST request to https://partner.microsoft.com/xdts/authorize is returning a 400 when entering the activation code.

There are a number of errors as well, including:
- TypeError: t.DisplayClaims is undefined

- Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://dc.services.visualstudio.com/v2/track. (Reason: CORS request did not succeed). Status code: (null).

On Edge:

Met with a spinning wheel after entering activation code.

- POST https://xdes.xboxlive.com/activation?accountId=[...] 404 (Not Found) InstrumentHooks.js:93
- Failed to load resource: the server responded with a status of 404 -- () /en-us/dashboard/survey/api/surveys/partner.microsoft.com_nps/null/[...]/appsAndGamesSuppressed:1

Final edit:
Upon the nth try, it finally worked. Try using Edge and kissing your rosary.

Clear Password and Upgrade Certificates are part of the Developer Mode settings on Xbox. Here I explain a little more about each one:

Clear Password: This is a key used to activate developer mode on your Xbox console. To activate developer mode, you need to go to partner.microsoft.com/xboxconfig/devices and enter the activation code displayed in the Dev Mode Activation app. You have a limited number of activations associated with your account.

Update certificates: These are certificates used to authenticate system updates. I didn't find specific information about update certificates in the system developer settings on Xbox.

Developer mode lets you develop and test games and apps right on your Xbox console. However, if you are not developing your own applications in the console, you do not need to enable developer mode.

If you click on the access key and update the certificates, nothing harmful should happen. However, if you are unsure, I would recommend that you do not click on these options unless you are sure what you are doing or are following specific instructions for app development.

I hope this clarifies your doubts. If you have more questions, don't hesitate to ask.
