Do not discard completed sign-in events.
When the signIns buffer is full, completed.tryEmit(id) can return false, and AccountRepository.signedIn() ignores that result. For an existing active account, the active-account collector does not run again because the ID is unchanged. SignInViewModel then treats the sign-in as successful without clearing AppViewModel.adding, so the setup screen can remain visible until the user cancels it.
Use the suspending emit(id) or another delivery mechanism that preserves completion events.

Make the pending-authorization claim atomic.
If two complete calls run concurrently, both can read the same pending authorization before either call to cancel() finishes. Both calls can then reach exchange, despite the single-exchange guarantee described here. Serialize the read-and-remove operation, or use an atomic claim, and test concurrent callbacks.

Consume the callback after completion claims it.
If the ViewModel is cleared after inbox.consume(callback) and before coordinator.complete(callback) finishes, coroutine cancellation can stop finish with the callback removed. The pending authorization then remains, but a recreated sign-in screen cannot process the callback from the inbox.
Move consumption after complete. The coordinator now claims non-mismatched authorizations before exchange, so retaining the callback during a canceled exchange does not allow the authorization to run again.

…count" Adding a second account could stop on "Setting up your account…" for good, even before a server was typed. Two causes met: - The first sign-in ends the sign-in screen itself: once the account is stored and active the app leaves it, and the work that took the callback was cancelled before it cleared either the callback from its inbox or the pending authorization. The next "Add account" found both, finished the old sign-in again, and signed in the account already there. The screen now takes the callback before acting on it, and the coordinator claims the pending authorization before it asks anything, so the same callback seen again finds nothing to finish. - Adding ended only when the active account changed. With every account shown together the first one is made active again at once, and an account signed in again was active already, so that change could be missed or never come. AccountRepository.signIns tells each sign-in, and adding ends on it. Assisted-by: Claude Code:claude-opus-5-5 Signed-off-by: Andy Scherzinger <info@andy-scherzinger.de>
