Jitsi meet queries

Hi,

We have installed jitsi meet on one of our AWS ec2 instance.

We are facing issues as:

  1. jitsi meet not working on Android mobile
  2. When we give custom room name it shows as insecure
  3. Room password not working
  4. How many users can connect to one room
  5. For a single room how much size of recording video MP4 takes
  6. How much data transfer for a single room
  7. Can we set username and password before entering any room
  8. Can we setup jitsi on Centos 6.4?

Regards,
Subodh
