Yep its an Enterprise provisioning profile.
Mine is an Adhoc provisioning profile. After the update, it seems to fix mine. It is building ok.
I also tested with an AppStore Distribution profile and it seems to work too.
Which update exactly?
An update made to the Ionic servers by the Ionic team
Thanks. I think the doc should provide the instructions for the XCode (v. 8) team profile creation.
It took me a while to find out this was the problem.
For the record, it is now possible (probably for a while) to signing temporarily for dev purposes, without having a Apple Dev account (yet).
