Sorry to ask this publicly, and nothing life or death, but please may I ask if a staff member may look at fault ticket no: 209319238 when convenient.
I originally raised this ticket on 12-Dec-2020 through the line fault reporting process, but the line fault itself seems to have since cleared.
However, I think banding has since been applied. Full details in the ticket.
Sorry and thanks again (I have messaged @Gandalf already sorry, but it's probably better here)
