I’ve already tried wiping all of my certificates and provisioning profiles from my Apple Developer account to no avail. Also, I don’t have an ad hoc profile.
I started out with letting Expo handle all the certificate provisioning, then did a exp build:ios -c so that I could use my own CSR to generate my own certificates and provisioning profiles but that didn’t work either. Since the error didn’t go away after using my own self-generated certificates, I decided to let Expo handle the certificate provisioning once more. This is my current state of affairs.
Got it. Yeah, I didn’t mean to recommend what you’ve already tried yourself. One thing I noticed in that github user’s post was that he deleted both development and production variants.
