Hello Sakib,
- If you're an active MCT with a Visual Studio Subscription, I recommend reaching out to Visual Studio Support. They specialize in addressing concerns regarding Visual Studio accounts and their associated benefits. You can submit an online request or contact them directly at 18007595474.
- Otherwise, if you don't have a Visual Studio Subscription and are only joining for free, please note that as per the recent announcement on this Microsoft 365 Developer Program - Microsoft 365 Developer Blog, registration for the M365 DEV Subscription is currently closed. This affects customers without a PAID & Active VSS. Any updates regarding when this will resume or when this feature will become available again will be announced on the above-mentioned blog.
If this is helpful please accept answer.
