Hi
Thanks for the answer.
Unfortunately the link you provide is no publicly available and I do not have an intercom account.
In my case I had to regenerate the profile with a developer computer with xcode (like I saw here iOS automatic provisioning does not use a profile with all devices included)
Adding the udid in bitrise test devices helped me because as far as I did that my builds failed until my provisioning profile contains the new udid.
As a conclusion, for me the io auto privisioning step requires a manual action to add new devices.
Regards
Seb
