When you make a change to your iOS entitlements, this change needs to be updated remotely on Apple's servers before making a production build. EAS Build automatically synchronizes capabilities on the Apple Developer Portal with your local entitlements configuration when you run
eas build. Capabilities are web services provided by Apple, think of them like AWS or Firebase services.
This feature can be disabled with
EXPO_NO_CAPABILITY_SYNC=1 eas build
In bare workflow apps, the entitlements are read from your
In managed workflow, the entitlements are read from the introspected Expo config. You can see what your introspected config looks like by running
expo config --type introspect in your project, then look for the
ios.entitlements object for the results.
If a supported entitlement is present in the entitlements file, then running
eas build will enable it on Apple Developer Portal. If the capability is already enabled, then EAS Build will skip it.
If a capability is enabled for your app remotely, but not present in the native entitlements file, then running
eas build will automatically disable it.
EAS Build will only enable capabilities that it has built-in support for, any unsupported entitlements must be manually enabled via Apple developer portal

for the time being. You can also refer to this Apple doc
for more information on manual setup.
