Hey 
I’m Lewis one of the engineers in the Open Banking team. I just wanted to reach out to say that we’re aware of this issue and that we’re sorry you’ve being impacted by it.
For some context Barclays made a change to the data format of the transactions they return to us, which has meant we’re unable to update the transaction feeds for connected Barclays credit cards & Barclaycard accounts. We’re working with Barclays to resolve this.
