Sign-in when restoring on TestFlight

Developing with unity2019

Sign out from iphone settings/sandbox account When calling Restore with the app downloaded from TestFlight, Authentication was called in iOS16.1 iOS16.2 iOS16.3, but I was only signed in to the sandbox and Restore failed.

When I signed in from the iphone settings and returned to the app, the restore was successful.

Is it because it's TestFlight that I signed in only to the sandbox?

Will signing in to iphone and restore succeed in Release?

On iOS16.0, when I signed out and started, Even if you open the iphone settings and sign in, Restore fails, I restarted the app and it worked.

Is this an iOS16.0 issue?

It won’t be successfully
