Sandbox subscription issue: "You don't currently qualify" for M365 Developer

Hello Microsoft Community Support Team,

I am currently taking an training course on Microsoft Power Platform, with a special focus on building chatbots using Microsoft Copilot Studio (formerly Power Virtual Agents), Power Automate, and Power Apps.

I wanted to set up a dedicated environment to practice the modules, configure cloud flows, and test the integrations. However, when I joined the Microsoft 365 Developer Program using my personal account, I encountered the following message:

"Thank you for joining. You don't currently qualify for a Microsoft 365 Developer Program sandbox subscription."

I do not intend to use this for commercial purposes; my sole objective is learning, studying the curriculum, and practicing developer scenarios for my training. Unfortunately, my university's IT administrator has disabled trial features on our student accounts, so creating my own developer sandbox is my only viable path to complete the practical exercises.

Could you please assist me in manually reviewing my profile or enabling the M365 E5 developer sandbox subscription for my account so I can continue with my Power Platform learning journey?

Thank you very much for your time and support.

Best regards,

Pablo
