Hello, Vincepicton.
Welcome to Microsoft Community, here your request will always be well received.
As we understand from your post, you are not able to Update your Certification Profile or schedule your Exam.
In this case it is most likely to be the cache of the MCP platform website storing the old profile information, once you navigated to the profile information area the requested data was found in the browser's cache (what is called a cache hit). Since the browsing data was deleted (cache included) when you accessed the same page again the browser could not find the requested data and had to retrieve it from the server (a cache miss).
Additionally, the error message "50040: Sorry, we are having a service interruption and we are unable to complete your transaction." Can occur when the information added to the profile either has characters that are not part of the basic Latin alphabet or when the formatting of the phone number is not correct. Remember the Microsoft Certification Profile have to match with your government ID.
For reference on the latter, when selecting the country, its indicator will be added automatically, sometimes users will input this country code in the "Area Code" (the code is often determined by region depending on the size of the country, or by service provider in the case of cellphone numbers) field causing the error.
We kindly advise you to follow the steps listed below and attempt to try the following troubleshooting:
Make sure to use an up-to-date browser. (e.g. Edge)
Clear cache and cookies. Make sure you check Preserve Favorites, website data and check both Temporary Internet Files and Cookies; then click Delete.
On the Delete Browsing History window, make sure to uncheck Preserve Favorites, website data and check both Temporary Internet Files and Cookies; then click Delete.
Allow all third-party cookies through the browser settings.
Please make sure that you have the latest version of the Edge browser or Internet explorer.
