I've added a new user in Bandhelper and the songs and set lists have ported over but not the layouts on their iPad. What do I need to do for them to be able to see the layouts I've set up on my laptop ?
If you already have layouts in your account that match this user's device screen size, you can edit those layouts and make sure they are assigned to that user and project.
If the user's device has a new screen size from your other devices, you can click Help > Utilities > Load Default Layouts on that device. (That should have run automatically if there were no existing layouts available to that user.)
