I accidentally deleted the Team Provisioning Profile:* in the Provisioning Portal, what should I do now? :/
As mentioned in one of the answers in Refresh devices in team provisioning profile managed by Xcode 7? , you can just delete and re-add the Apple ID in the Preferences->Accounts panel, which should regenerate the xcode-managed team provisioning profiles in the Developer Center. (Other answers here and elsewhere suggest to right-click provisioning profiles, which doesn't work for me, or apply to older versions of XCode for which the answers no longer apply.)
