Yes, Check in Check out Sheets are across an organization and not limited to one device. Therefore, if a admin creates a Check in Sheet on their device, it will appear for all other admins in that organization that have access to the group that the Check In Sheet is based on.
Please note that when a sheet has been created and any new members/ admins are added to the org/ group, the admin who has access to the sheet needs to sync the members, by selecting ‘sync member’ (click on the 3 dots) to see the updated list and for the new admin to be added.
Please note that if they do NOT see it, they should "Update Member Records".
