collab-app-repair

Diagnoses and repairs Microsoft Teams, Slack, Zoom, and Cisco Webex problems including media issues (mic, camera, speaker), stuck cache, stale meeting metadata, and search-index failures. Preserves the user's signed-in state — clears app cache and resets A/V device selection without forcing the user to sign back in. Use when the user reports the collab app is misbehaving but their account credentials are still valid.
