I get the above error when trying to build my app and publish to TestFlight.
I have gone in circles trying to clear out and recreate certificates and provisioning profiles, with no luck.
I was able to create this successfully when using a first certificate, but as TestFlight errored out because I had no devices attached to that provisioning profile, I had to recreate the certificate. Since doing this I have encountered this error.
Can someone give me any clues?
