Setting up card payments with PAYUNi or SunPay now works as expected.
- Your PAYUNi and SunPay details are now kept when you save your payment settings, instead of being dropped.
- The SunPay secure key is now saved exactly as you entered it.
- There is no longer a separate test mode switch. Payments run in the provider's test environment only while you are using the test merchant ID that PAYUNi or SunPay gave you, and switch to live payments as soon as you enter your own merchant ID.
