Significant performance latency and slow response times in Microsoft 365 Copilot.

My Microsoft 365 Copilot is running significantly slower than normal and taking an unusually long time to process information. Previously, queries processed within seconds or moments to support my standard workflow, but responses are now experiencing severe latency, disrupting my daily tasks.

Please investigate potential service degradation, tenant-level throttling, or backend latency affecting my account.

    Hi @Denoto, Phil

    I understand how disruptive the slowdown is. Since this involves a personal account, forum moderators cannot access backend diagnostics or investigate account-level latency directly.

    Please test Copilot in an InPrivate window and, if possible, on another device or network. If it remains slow, submit feedback from within Copilot immediately after a delayed response, then contact Microsoft Support through the Get Help app. Include the approximate time of the issue, response duration, affected Copilot app, and whether it occurs with all prompts. This will give Support the information needed to investigate further.

    Thank you for your time and have a nice day
