I had implemented MultiUserChat in my project using Smack(I am using Openfire server in backend)
Create a new group, invite the user to a group is working fine. Normal group chat is working fine for the first time.
If any user's connection is restarted then that user can not receive a message from the group (If he/she send a message to group it is received by other users). On connection restart, I had rejoined user to that group. Because of XEP-0045, say's if the user will go offline it will automatically remove from group
I don't understand why user not receive messages from the group if a connection is a restart. Can you help me
