Help Me Please! Suddenly Facebook page Instream ad monetize option not showing!

Last time when I checked Instream ad monetize option was visible. Facebook page need total 60,000 mins watch time to apply for Instream ad on videos. My page was almost 51,000 mins watch time last time when I checked. Now i am sure i have more than 60,000 mins watch time. But my bad luck is this option isn’t invisible.

I contacted to facebook twice but got no reply at all. Can anyone let me know how can I fix this issue?

Below is screenshot attached
