Private league management

[Gaurav Khanolkar]

Hi, I created a private league today to play with a group of friends (10-12 in total)
I created the league and shared the league name, code and invited them individually.
Yet only two of them were able to join without any problems.
The rest of the people would either not see the league or not be able to join or I would not get their requests to join the league.
Any help on this matter would be useful.

Later to deal with this problem, I made the league public, doing so, I was able to add two more friends but unfortunately an outsider was able to join in as well and now has blocked one of the required teams.

Can you please help?
