Apple Sign-In capability reset during EAS build

Summary

We want to use "Sign in with Apple" under a different primary App ID, and have selected the "Group with an existing primary App ID" option in the Apple Developer Portal (under Identifiers > <bundle_id> Capabilities > Apple Sign-In). However, when running an EAS build, this setting is automatically reset to "Enable as a primary App ID."

This seems to occur during the "Synced capabilities: Enabled: Sign In with Apple" step in the build process.

Is there a way to prevent this reset, or a configuration option in EAS that would allow us to maintain the "Group with an existing primary App ID" setting during builds?

Managed or bare?

Reproducible demo or steps to reproduce from a blank project

• Create a managed Expo project
• In the Apple Developer Portal go to Identifiers > <bundle_id> > Capabilities > Sign in with Apple, choose "Group with an existing primary App ID".
• Run eas build --platform ios
• The above setting is then reset to "Enable as a primary App ID"

It seems likely to be a bug I will check it. For now, you can do EXPO_NO_CAPABILITY_SYNC=1 eas build https://docs.expo.dev/build-reference/ios-capabilities/.
