Halifax doesn't show in linked accounts despite 'successfully linked'

This has happened for the last week at least. I’m unable to see Halifax in my linked accounts despite it saying successfully linked. I’ve tried numerous times and closed the app. I’ve also got issues with Tesco Credit Card linking: Linked Tesco Credit Card no longer refreshing - #6 by rubengonzalez

Other accounts work fine (e.g. Lloyds)

Still not working just checked again.

(Tesco Credit Card looks like it is though).
