    But you don’t need to turn off "Automatically manage signing" in order to upload to TestFlight, so just turn it back on and stop worrying about this issue.

    You can have a limited number of Distribution Certificates (2 or 3 if I recall) on your Developer Portal.

    As you can see in your second image in the second part those exist but are not in your keychain on this laptop.

    2 options at this point:

    • Delete all distribution certs from the portal and recreate one (either from Xcode or the old way)
    • Export one of them from Keychain, with it’s private key (p12 format) from the other computer on which it must be (right click > Export > Choose p12)
