macOS Beta Tester unable to enter Sandbox Test User Apple ID

I have a Beta version of my macOS App that I would like a Test User to be able to test. They already have the released version installed on their machine, so this is a 2nd version. When they start it up though, the "Apple-ID" text box is greyed out and uneditable and contains their "real" Apple ID. They are not able to even enter the Sandbox Test User information.


What needs to be done to trigger the "new" Apple ID to be used?


Just FYI, yes all the other get "Hardware-UUID", new Provisioning Profile, Archive, Export for Development stuff has been done. It has been successfully installed/started by others. But they are previous Beta testers and this person is a new Beta tester. What are the requirements for being able to use a different (Test) Apple ID for the first time?

The TestFlight app operates in the sandbox but it does that 'automatically' by replicating the user's production environment username and password with an identical username and password in the sandbox - so it appears to the user like they are using their production account.

This is a macOS App so no TestFlight. They signed out of the Mac App Store and that helped, but now they're getting the dreaded "App is Damaged" message when they log in using the Sandbox Test Apple ID and I'm still trying to work out why. Same binary is working for other test users.
