I'm trying to build my Expo app. I already built it for Android, but now I'm struggling to create a release on iOS to upload on TestFlight. I have the apple developer account of my university, and they added our bundle ID there(I'm not an admin). When I try to build with EAS, it requires a p12 file. So, I tried to generate it in this way: From Keychain Access I created a CSR(by adding my mail and name) and then on Apple Developers I uploaded it(Certificates > +), so I downloaded a .cer file I opened the .cer on Keychain Access and I dragged it under "login" section From there I exported the p12 file But that p12 gives me always this error when I run npx eas build --platform ios : Provided Distribution Certificate is no longer valid on Apple's server after submitting the p12 file on eas console. Can someone help us? Thanks in advance for your availability :)
