To change or edit your debt account (where payments are sent):
First, open your Qoins app. Click on the upcoming payment from the UpcomingPayments card on the app, then tap the three-dot menu in the top right-hand corner. From there you will be able to select the option to “Change payment destination” and then change the information of the current account, or add a new debt account.
Once this is done, your payments will go to the new debt account you've added. This will not affect any already sent payments.
