I'm trying to sign-in with a Sandbox account with my iOS simulator. Using Xcode 26 beta 7. After I sign in, the button goes inactive for a few seconds but then nothing happens. It does not actually sign me in.
Sandbox account won't sign in
In the sandbox, you can fetch In-App Purchase information in the Simulator. However, you cannot purchase them.To test purchasing In-App Purchases in the sandbox, run your app on a device. For more information, see Testing In-App Purchases with sandbox.
Any update or workaround that you have found for this issue?
