Before contacting support
Safe first checks
Installation or startup
Confirm a supported Windows x64 environment, WebView2 availability and write access to the per-user local application-data location.
Sign-in
Confirm the customer-owned app is a public client, both loopback redirects are exact, delegated permissions are configured and no client secret is present.
Discovery
Check the technical account connection, workload-level status, delegated scope evidence and the sanitized error code. Preserve the last good inventory while investigating.
Licensing
Confirm the tenant boundary, edition, validity period and whether the current operation is Community or Professional-only.
Professional write
Confirm delegated write scope, runtime evidence, operation switch, selected scope, safeguard and approval—not only the license.
Documentation
Use the guidance for the exact installed version because the product remains in active development.
