In existing versions of Asperato ONE application it is currently possible to click "Process payment" button multiple times, when taking an immediate payment from authorisation. Note that "Process payment" button is displayed in a dialog window for Lightning and on a new page for Classic interface.
When processing payments from an authorisation, by clicking "Process payment" button multiple times, users will notice that this results in duplicate payment records. Therefore we advise to ensure that "Process payment" button is clicked only once by a user during each payment request, until a fix is implemented by the team.
