I deleted/rejoined my Microsoft 365 Developer Program profile and I received the welcome email confirming that a new instant sandbox was created.

Hi Guthierres Cavalcante

Thank you for contacting Microsoft Q&A and providing the details of your issue. 

Based on the information you shared, it appears that the dashboard may still be synchronizing the new Microsoft 365 Developer Program sandbox information after the old subscription was deleted and the program profile was recreated. 

Please note that this is a user‑to‑user support forum, we do not have access to Microsoft 365 Developer Program backend systems or the ability to directly check the provisioning status of your sandbox subscription. 

In this case, you may try using the “Report errors” option located at the bottom left of the Microsoft 365 Developer Program dashboard to reach the Microsoft 365 Developer Program support team for further review. 

Thank you for your understanding.
