Hey @alucke
Sorry this is so confusing, I’ve dug up an older forum posts where other users have had luck. Error while gathering & validating credentials - #18 - does this help you out at all?
You’re going to want to run it as exp build:ios -c
You’re going to want to make sure you’ve logged into apple developer and accept terms and conditions.
You will want to revert your apple distribution cert and let Expo handle it.
