Hi all, Having the same problem here. We develop apps (agency) and surely this cannot be true whereby we cannot log in to submit apps for our customers using a unique development device? Is this really what this error is suggesting, that we cannot develop for multiple customers using the same devices? If so, I agree with the comments above whereby this really will be the death of development on Apple. Anyone else have any info? Thanks.

@eskimo Appreciate that you do not have access to resolve account issues, but this does not seem to be related to accounts, more that there has been a change whereby developers are now unable to log into users accounts to submit the apps via Xcode if the device is present on other accounts (which it will be). Where can one see any changes that have been made in regards to this and how should we report this to Apple (as a developer) as it does not directly relate to any particular account? Apple have suggested to me that I refer this back to the customer to report, but if the error message relates to our devices (used to publish the customers app via Xcode) then surely the customer is going to be told it does not relate to their account or device and we're going to be in a loop. Who/How should we log this with Apple? Thank you.
