Echo after app crash and re-join

Recently faced an issue in Jitsi-Meet iOS.
Somehow app get crashed and after crash when I joined the same room again, observed echo from previous connection.
So is it possible to check any previous active connection and disconnect if it is active?

Thanks.

That’s impossible if the app crashed, as all connections are closed by the system. Maybe the app didn’t actually crash? Please walk us through the problem in more detail.
