I think that might be a different issue, the other bug was about when an entire peer goes down. Normal presence should work as expected. @Florimond could you verify?

@IliasP91 I was about to say it works properly according to my tests both on latest and edge as well as by running Emitter in VS Code. Then I managed to reproduce the issue once on docker lastest, but never again. Do you have a way to reproduce the issue consistently?

hi guys, ill try to create a small solution that reproduces the issue, ill keep you updated

hmm very interesting, just created a demo proj and attempted to recreate this, it worked fine as v2.8 whereas before it was not raising an unsubscribe event if I just closed a client console app. Now it does. Could it be that something has changed in the last 2 weeks on the latest branch/docker build?
Regardless here are the repro steps and the demo repo:
https://github.com/IliasP91/emitter-io-subscription-issue-repro
Repro steps:
Create a new docker instance with the latest image
docker run -d --name emitter-latest -p 8080:8080 -e EMITTER_LICENSE=PfA8IEfJReKdp2pWUOw_MVsWWUsaPdPhV79_C75M85nEsaz3ECnmNla4j_G8Ph8dkLpJkSH-5sqjDrG13OMLAQ:3 --restart=unless-stopped emitter/server:latest
Create a read,write,presence key on the new instance for channel 'test/'
Copy key to both console apps
Build and run Run.bat
Close one of the 5 opened clients
Type something on the broadcaster and press enter to invoke a presence request and see the list of connected clients
Feel free to close this if you think it doesnt require further investigation

I reproduced a similar behavior when I subscribe twice to the same channel with the same client. There is a counter that is incremented twice, and the other clients are only notified of a disconnection if this counter is at 0. But since, by exiting the program, you only produce one disconnection event, the counter is still greater than 0, and the other clients are never notified.
I'll discuss the issue with @kelindar to make sure I understand what was the intention behind this piece of code and fix it properly.

This commit should fix your issue: 9e628aa
Don't hesitate to test and confirm the fix. Closing the issue for now.
