@tony1963 I am not a member of their team, but I am from the same country (Bangladesh), although I currently live abroad (I personally know the founders). There is a massive student protest ongoing within the country, and the government has shut down the internet for the past four days. That is possibly why they are not responding to any queries and possibly site being down. You can check the situation on YouTube if you want more information. As of today, no one knows when the situation will improve.
