To add on top of my original question - will it be mandatory at all?

Thanks Eskimo! I also verified it by trying it with a non Admin and non Account holder account and I got an error.

After doing some additional checks it turns out that both App Manager and Developer roles can register UDID if they have access to Certificates, Identifiers & Profiles. Role Permissions list under the Search for "Add UDIDs" item https://help.apple.com/app-store-connect/#/deve5f9a89d7 IMHO, that's a shame because it basically means that there is no control over the devices added to the account since Developers are responsible for adding their own devices.

Same here. Crashing on dyld: Symbol not found: _vfork when running on iOS 13.7 simulator. Both the Thread Sanitizer and the Address Sanitizer are disabled as per other threads: https://developer.apple.com/forums/thread/695167 https://developer.apple.com/forums/thread/686884 I've the following setup: MacBook Pro with M1 Pro silicon Monterey 12.3.1 Xcode 13.3.1
