Team Queues are available in the GQueues iOS app.

To view them open the side panel and choose Team Queues.

Just like in the desktop version, you'll only be able to perform actions in teams based on the permissions set by your team member role.

Performing those actions works the same in Team Queues as it does for My Queues.

It is not currently possible to create a team, view team members, leave a team, or access team settings from the mobile app. Those actions should be taken on the web version of your account.
