I can't schedule an exam.
After choosing the country and clicking the "Schedule Exam" button it loads the next page but 3 seconds later it loads a blank page with no error message in the html.
After digging I found a network error:
"error_description: "AADSTS70000: The user could not be authenticated as the grant is expired. The user must sign in again.\r\nTrace ID: bc1ebfe7-2f4a-407d-8c8a-dd890794ac00\r\nCorrelation ID: 1745f6a4-e668-4b7a-9a0d-c7daa25f18e3\r\nTimestamp: 2023-01-17 19:19:49Z".
I tried different browsers, log off and back in, and clear the cache.
Hopefully the provided information helps finding the issue.
