Hi,  
I’m creating a subsession and adding users to it as follows. This all seems to work correctly

```auto
const createResponse = await subsessionClient.createSubsessions(1);
const subsession = createResponse[0];

for (const u of participantsToAdd) {
	 await subsessionClient.assignUserToSubsession(u.userId, subsession.subsessionId);
}

await subsessionClient.openSubsessions([subsession], {
	 isAutoJoinSubsession: true,
	 isAutoMoveBackToMainSession: true,
	 waitSeconds: 0
});

await subsessionClient.joinSubsession(subsession.subsessionId);

```

When in the subsession, calling `client.removeUser()` fails after a few seconds with

```auto
{
	"type": "OPERATION_TIMEOUT",
	"errorCode": 1
}

```

This seems to only affect subsessions, calling `removeUser()` from the main session works as expected.

I’m having a possibly related issue with `subsessionClient.moveBackToMainSession()` which I’ll add as a separate ticket

Hey @Jonathan11

Thanks for your feedback.

This is indeed an issue with our Video SDK, and we will fix it in the next release.

Thanks
