## Updates from Duo Security
### 2025-09-29 09:46 UTC: investigating
We are current investigating issue where custom attributes are not being synced from Entra ID to Duo. Entra ID sync is working as expected with standard attributes.

We are continuing to investigate this.
Please pause your Entra ID sync if you are using any custom attributes as sync attributes, and, if possible, do not run a full manual sync until the issue is resolved. As a workaround, an admin can sync individual users by following the instructions in our guide below:
