We've identified a recent deployment that's causing some users to experience issues signing into Teams Free on mobile iOS and Android devices. We've rolled back the offending deployment, and we're monitoring as we're seeing the impact recover.
We’ve isolated the root cause of impact to a portion of infrastructure that controls smart responses, the infrastructure isn't operating at expected thresholds and is resulting in impact. This issue could impact any user attempting to utilize Microsoft Copilot to generate responses. We’re restarting the affected machines and our monitoring shows signs of improvement.
