Bugs Found in Traffic Flow: Idle Tycoon Game for iOS
Traffic Flow: Idle Tycoon Game offers a calm, easy-to-learn idle game that drives you to build your own transportation empire. Players move passengers around to fit them all into seats as well as upgrade check-in, boarding, and seating speeds. Along the way, one small plane out of Dublin grows into a transport network of buses, trains, ships, and trucks. Neon visuals and the absence of timers or fail states make it easy to pick up and put down at any moment.
We enjoyed testing Traffic Flow as part of QAwerk’s regular bug crawl. The core loop is straightforward and works well, but several supporting features do have a few issues, including account deletion, audio, and purchase restoration flows. You’ll find the detailed report below.
User is unable to delete account due to ‘Could not confirm deletion’ error
Major

The account is not deleted. The ‘Could not confirm deletion. Please try again. Your local progress is saved.’ error message is displayed. Retrying the operation does not allow the user to complete the account deletion.
The account should be successfully deleted after the user confirms the deletion request. If the deletion cannot be completed, the app should display a message giving a clear reason for the failure.

A clear result message should be displayed after completing the ‘Restore Purchases’ flow, informing the user whether purchases were successfully restored, no eligible purchases were found, or an error occurred.
During testing, we identified several issues in key supporting functionality. The most significant one affects account management and shows a recurring error when trying to delete an account. Overall, the core gameplay remains accessible, but improving account management, audio functionality, and purchase-related feedback would make the application more reliable and provide a clearer user experience.
