it drive me crazy !!! because its so difficult to add new member.
now we are 10 people and I cannot increase it as I am trying to pay more.
its been already more than 30 hours to ask about this.
and new member can never receive invitation email from atlassian
we are using this for more efficient team working but I am spending too much time to manage new people !!!
