This error is very easy to resolve. It occurs when we are trying to close an event but scan the QR code of a different event. You need to scan the QR code of the active event to close it. Once it is closed, you can activate a new one.
Go to Settings in the app;
Check the event number (at the top of the settings list);
Go to the event list on Touchpix.com and find the same event number;
Open the QR code and scan it to close the event.
The second cause, less usual to find, is having the app outdated. During 2024 we made the transition to our New UI. The old app, if not updated, is not compatible with the new event manager.
Additionally, verify that your subscription is active and ensure the device has a stable internet connection while managing events.
How does the Old UI look?
Take a look at these screenshots, which correspond with the Old User Interface. Additionally, ensure that the app is updated to avoid compatibility issues with event management.
