Hello Brendan,
Thank you for using Powerlynx.
Most likely, you have enabled the “Trial Sessions” feature, which provides temporary Internet access to the end-user after clicking the “Buy” button.
You can find more information about this feature here: https://forum.powerlynx.app/t/mikrotik-walled-garden/19/10?u=alex
Please check if the “Trial Sessions” feature is enabled. If it is, kindly disable it by navigating to Config > Captive Portal and try again.
If you need further assistance, please feel free to contact us at support@powerlynx.app.
Best regards,
Alex
