Chrome bank feed plugin - Santander not working

After working successfully for quite some time my bank plug-in with Santander has stopped working. It’s really irritating has anybody else had the same problem?
I’ve asked this question 4 or five times recently but have had no response

Hi @hmichaelcumming

We’ve not received any reports of any issues, and I’m not aware of any. Would you kindly provide me with a few more details (e.g. how far will it allow you to go? What part of it isn’t working?) and I’ll happily take a look for you?

Please accept my apologies on this as we aim to respond all queries within an hour during office hours. I’m not able to find any previous posts from yourself relating to this however. Where did you post these queries previously?
