Developing First Ever IOS App - Have Very Specific Questions to Unblock my Testing

I have developed an app that I had been testing on the hardware device with the developer profile signed builds, I had setup a CloudKit container in development mode and also had tested with Production mode and they are working as expected. I have also tested storekit auto renewal subscriptions using Storekit Config file and all of that is working on the hardware device with the developer profile signed builds.

Now comes the Fun Part, I want to use the Distribution profile to test the app for production readiness, I had created a distribution profile and had set that up in the Release under target of the app in Xcode, I have also created sandbox tester account (which is showing inactive even after 7 days - though I am also logged in with this sandbox tester account on a hardware device and under developer setting it shows as a sandbox tester account)

All the subscriptions are showing Ready to Submit in the App Store Connect.

I need help understand this whole flow, how to ensure I can test CloudKit and storekit for production readiness and then publish my app for the review.

Thank you.
