CloudKit not working on actual iOS device

I've developed an app that contains an inbox that displays message from a CloudKit container. Works perfectly on simulator. Once I tried to run it on a phone..in Xcode debug environment and TestFlight it is unable to complete any transactions with production database. I'm running out of ideas. So far I have tried:

  • Verify settings between debug and release in Signing & Capabilities
  • Add CloudKit.framework to Framework, Libraries, and Embedded Content
  • Verify record and key names
  • verify .entitlements files

Please help!
