I enabled this option

Multiple Sessions per User
Allow multiple concurrent VPN connections for a user (automatically disabled when static VPN IP addresses are configured for users)

And I added

duplicate-cn

On both the boxes Server Config Directives and Server Config Directives

I propagated options to running server, redownloaded .ovpn on an Android and on an iPad.

When iPad connect with the same user of Android, Android is kicked off, and viceversa.

What should I check to enable concurrent connection?

You don't need to add that parameter. Just enable the option in Advanced VPN.

The error message you get will likely say that user specific properties prevented the connection. Go to user permissions, create a new user, and set nothing on that user at all, except a password if you use local authentication. Try again with that account.
