Dear Flavia.Admin
Thanks for choosing Microsoft Community.
Based on your description, I know the scenario you met. For this, could you please be kindly to make sure you did as the following KB said. For this,, please be kindly to check Manage devices in Microsoft Entra ID using the Microsoft Entra admin center - Microsoft Entra ID | Microsoft Learn and How to manage stale devices in Microsoft Entra ID - Microsoft Entra ID | Microsoft Learn.
If you did as offical KB said bu still cannot see the option, for this, I think the cause of the problem is most likely due to an error on the server backend, because our forum lacks relevant knowledge and permissions, so to better help you, please kindly try to create a service ticket in the Microsoft 365 admin center to support > service requests through navigation, as they have more access permissions than on this forum, and professional engineers will further help you.
Thanks in advance for your understanding! Your patience and cooperation will be highly appreciated. Hope you all the best!
Have a nice day.
Sincerely
Katherine
