New user cannot access free prototype - "Error fetching subscription"

Hello,

Since September 7, 2026, a newly invited user has been unable to access my app due to this error: “Error fetching subscription”

My setup:

  • free plan
  • the app is a prototype and is not deployed.
  • app info shows 2 monthly users for this app
  • google sign-in is required.
  • the new user has been added to Manage Users with “use app” permission.

Testing results:

  • the app owner and existing test user can still access the app.
  • the new user signs in with the exact Google account added to Mange users but receives the error.
  • The problem occurs on both iPhone and desktop chrome
  • The mobile app displays “App Load Error”
  • Clicking the support link on the error page also produces an “Internal Server Error” at /help.
  • Retrying several hours later did not resolve the issue.

Could you please help determine whether this is a service issue or an account/licensing issue, and advise on the next steps?

Thank you very much.

Perhaps you were affected by this?

@NAKA, has this been resolved?
