Payment error message: InLimbo payment

The payment appears to have been processed correctly, however, a red message will pop up on the payment confirmation screen.

This means that the Confirm button was clicked twice at that time where payment worked as expected and then refused to submit the payment a second time because the first one was in progress.

The first payment succeeded which is why there's the success message (from the first payment attempt) and the error message (from the second attempt).
