Unity Services

Vivox login is also normal,
Channel access / other user access event normal operation confirmed.
When leaving the channel, the error occurred.
I haven’t been able to figure out the current cause.
I am asking for help.

I think the problem is on line 21. Instead of loginSession.DeleteChannelSession(curChannelInfo.curJoinChannel); use loginSession.DeleteChannelSession(channelSession); and see if that works
