So, the Channel Presence feature actually notifies when a channel is connected/disconnected as opposted to created/destroyed?
If this is correct, then how can I find out when the channel that was created on the server-side has been closed and not simply disconnected? I guess I'm confused about creating vs. connecting and destroying vs. disconnecting Here's what I'm doing: * Client requests a token using "client ID" * If "client ID" already has a token (this info is saved in the datastore when the channel is created server-side) THEN send the client the token, and call channel.open(token) on client-side * If "client ID" doesn't have a token (meaning the info doesn't exist in the datastore), then create a new channel and send client the token, which in turn calls channel.open(token) * When Channel Presence detects a disconnect, delete the info stored in the datastore (this is maybe where I've gone wrong, since the channel is not destroyed, but simply disconnected) Thank you for your help.
