I was able to get around this issue by manually creating the P12 distribution certs and pointing to them instead of having Expo create them for me. The other certs (provisioning profile and push notification cert) were created automatically by Expo successfully.
Hey @oldo, glad you found a workaround, but I’m curious if clearing the credentials (by passing the -c flag to clear all creds, or --clear-dist-cert just for the distribution certifcate) would have fixed it, that way you don’t have to manually create it
