Shared keychain is not working with App centre build

[compfall]

So basically two Apps under the same team are sharing information stored in the shared keychain of the iOS devices.

The apps are working fine with builds coming from TestFlight and if we run the apps from Xcode.
One app stores the information on the device, and the other app can fetch it through the shared keychain.

However, when we tried the builds coming from App centre, they are not working as expected.

can someone help me out with this issue please?
Thanks in advance
