We need functionality to remove a single user from active multiuser conversation. Current SDK (4.1) does not support this.
Below is the log showing this:

Hi,

Thank you for your qeustion.

You can call RemoveParticipantAddress API when conversation is in draft mode and has not sent to server yet. This API is not supported for active conversations, so capability is not allowed.

Hi Rumata,

It is so easy to say `not allowed`for you. But It is not so easy to say `not allowed ` to the customer, where all free of charge applications support this feature.
We already talked with product house about this feature, they are going to add it to chat application.

regards,
