Can't I use the same Photon ID in two Titles?

Hello.

There was a problem with the PlayFab verification process.

I'm developing with Photon Quantum, and I launched the game on Steam.

Patches are out about twice a month.

PlayFab doesn't seem to have a function to distinguish the data or status of the

development version and the live version.

So, when setting the Title Data data, the DEV_ string is attached to the Key to

separate the development version data from the live version data.

I don't think this is safe, so I'm trying another way.

So I made another PlayFab Title to differentiate between the development version and the live version.

The problem is that the existing PlayFab is not authenticated because of the newly created title.

After entering the newly created Title Add-ons, I installed Photon.

Realtime App ID and Chat App ID were set as they were.

I thought it would not affect the existing PlayFab Title, but

authentication is failing in the existing PlayFab Title.

The log was printed as below.

PlayFab /Client/GetPhotonAuthenticationToken: PhotonApplicationNotFound

When using the same Photon Add-on in two PlayFab Titles, can't I use the same Realtime App ID?
