I’ve had similar with Halifax; credit card repayment (£50) and mortgage protection (£42.27) get combined in to one prediction of £92.27 and then split into a fortnightly payment of £46.
Going to work round it by transferring the CC balance to my Barclaycard and hope it sorts itself out after a few months of no Hfx CC payments.
This has been raised with our Product team who have spoken with Emma.
They are currently using an older version of our API which is causing the issue you’ve raised. They’ve advised they’re planning to move to an updated version of our API in the coming weeks, so hopefully this issue will be resolved soon.
Thank you for brining this to our attention
