Before you contact support
Attach a diagnostics export.
When contacting support, attach a diagnostics export: open Enterprise Contacts → Settings → Export diagnostics and share the file. It is a plain-text report of app, device, and configuration state, per-source sync status, and logs — it contains no contact content and no tokens, and speeds up every support case.
