Have just noticed that Apple redesigned iOS Dev Center this weekend.
I need to add a couple of devices to an existing Ad-Hoc provisioning profile. But when I push Edit button, I can change only Name and App ID.
Is it any way to do it except of the obvious one: to delete the existing profile and create a new one with all required devices?
UPD.
Now I can edit the list of devices for development profiles, but not for distribution.

Can edit devices for new distribution profiles, but can't do it for old.
Apple fixed it. So it was a bug. Now you can edit your embedded device list, even if it's an Ad Hoc distribution profile.
