Few points

1. i have been trying to open the website properly and it take ages to open i.e. ~10min and everything seems slow
2. exchange page load is very very very slow
3. I cant enter my phone number in profile , hence cant enable 2FA security


so apparently only way to get the COSS is through COSS website, or there is another way ?  (hoping this is a beta website but actual website will be faster)
