A number of times people are unable to join as Brave is telling them room is “full”, even when only one, two or three of us are there! This happens quite often in my experience.
This is very frustrating as I try to get people over to Brave Talk, but in the end they force us to go to Google Meet because “It just works”
Also, in general this 4-person limit is not a good idea - too limiting so we cannot attract for serious meetings for more adoption. It could also help solve the former problem (indirectly). A more sensible number would be 8, so that most small meetings can be accomodated and it can become more normal to use Brave Talk.
