I am confused about how to add a trusted phone number and trusted device to my company's main Apple Account, the one who is the Account Holder. I understand that we need to: Obtain an iOS device that is associated with a phone line. Create an Apple ID that is controlled by my company. Add the Apple ID to the device. Set up 2 factor authentication. Sign into https://appleid.apple.com/account/manage#!&page=signin with the new ID and select Account Security. Then select to add a new Trusted Number. Enter the phone number assigned to this new device and continue. Now we have a backup account and device that can be used to access the account if the Account Holder or the device associated with the Account Holder is not available. Is this correct? Do we have to have a device that has a phone number? Someone suggested that you could use an iPod Touch as a second device, but you cannot assign a phone number to an iPod Touch, right? I am very very interested in following best practices with regard to this and would appreciate any information or links to information on best practices.

My company has submitted 2 apps to the iOS store. One is for a "Producer" and the other is for a "Driver".Producers will request a pickup of a commodity. This request is assigned to a Driver and the Driver will follow directions to get to the Producer, pickup the load, and then transport the item to the destination.The Producer App gives the Producer visability of where the Driver is. We also have a web app that allows us to see wheree the Drivers are.The Producer App was approved and is in the App sgtore.The Driver App has been rejected:Guideline 2.5.4 - Performance - Software RequirementsWe noticed that your app declares support for location in the UIBackgroundModes key in your Info.plist file but does not have any features that require persistent location. Specifically, your app uses location background mode for the sole purpose of tracking employees, which is not appropriate on the App Store.Next StepsTo resolve this issue, please revise your app to include additional features for your users that require the persistent use of real-time location updates while the app is in the background.The app DOES have other features: Drivers can submitt invoices direcectly from the app, and can then get paid sooner. The Drivers are not our employees, they work for themselves. They don't have to use the app. We do ask for permissions. We have appealed and added information concerning the other features of the app, but we are rejected every time. I am kind of at a loss as to what we can do.All of our apps are built in Xamarin, if that is of any help.Any suggestions would be greatly appreciated.Bryan
