Root cause: A recent service update intending to improve service authentication produced an impacting token refresh issue that prevented admins’ access to the Microsoft Teams Call Quality dashboard. <\/p>\n

Next steps:
– We’re further analyzing the offending service authentication update to help us improve our pre-deployment testing and validations.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
