Fabric mac app 2.6.11 will not get new provisioning profiles from xcode 8.3.2. After adding new device ids to developer.apple.com, going to Xcode File -> Preferences -> Accounts and clicking on Download All (no other option is offered) and going into Fabric, Archive, Distribute - the devices are still showing as not being added to the provisioning profile.
There is no longer the option of deleting profiles in XCode. There is only Download All.
