If you encounter any issues, please look for a troubleshooting article on this page: Resolve Issues

Note: There might be a delay in propagating the SSO parameters from Microsoft Entra ID. To avoid issues with configuring SSO, we recommend enabling SSO on the Grammarly side 1–2 hours after setting up the Grammarly app in Microsoft Entra ID.
