Question Does "PresenceSubscription" in VIvox work?

Hello

I would like to do the following with Vivox
1, Get the online status of other users
2, Detect when other users log in and log out

To do this, I would like to use "PresenceSubscription" to monitor "Location".

However, when the same user logs in a second time, the Location is not updated.

Environment
Unity2021.3
VIvox: 15.1.190400-pre.1

The situation is similar to this article.
PresenceSubscription stops working after subscribed accounts logs out and in again

Thank you

 

Hello

We cannot proceed with our own project until this issue is resolved.

If PresenceSubscription is not working, we need to look into another service ASAP.

We would appreciate an official response as soon as possible.

Thank you.
