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

Hi Pablo, the sandbox qualification decision is automated and community members generally cannot enable it manually. The Developer Program is intended for active Microsoft 365 development and eligibility can depend on qualifying subscriptions or partner/developer activity. For your course, check the free Power Apps Developer Plan, create a developer environment in Power Platform if your account permits it, and use Microsoft Learn's temporary sandboxes where offered. Your training provider may also have a lab tenant. If the course specifically requires an M365 E5 tenant, ask the provider or Microsoft support which approved lab option they recommend rather than using a production tenant.
