Smack 4.3.2, Android 9.
When sending a large number (~50) of messages continuously (in a loop) using MultiUserChatLight.sendMessage, it stops sending after 30 or so (that number varies every time).
This does not happen in a private chat where the sender does not receive a copy of the message as it does in a MUC Light chat. Perhaps the incoming messages have something to do with this behaviour?
Any advice? Many thanks in advance.
