@Enzo Faranda Thanks for posting in our Q&A. From your description, I know that we have deployed a configuration policy but it need much time (over 2 working days) to be applied. If there is anything misunderstanding, please feel free to let us know.
For this issue, I have done some search. Normally, device will get the policy or profile on its next scheduled check-in with the Intune service about every 8 hours.

Given this strange situation, it seems that background log analysis may be needed. With the limitation of Q&A, it is better to create an online support ticket to handle this issue. It is free. Here is the online support link and hope it will be resolved as soon as possible.
