The charts haven’t been updated since Monday and the same price is being displayed today as it was then and this is across all accounts.
Even when looking outside of T212 for information the same old Monday data is all that is available but I cannot discover what has happened here, does anyone know?
Something to do with the AZ buyout?

Financial considerations
The total consideration paid to the Alexion shareholders was approximately $13.3bn in cash and 236,321,411 new AstraZeneca shares (approximately 94% of which will be represented by new AstraZeneca American Depositary Shares (ADSs)).
Admission of the new AstraZeneca shares issued to Alexion shareholders to listing on the premium listing segment of the official list of the Financial Conduct Authority (FCA) and to the trading on the London Stock Exchange’s main market for listed securities has been approved and will be effective at 08:00 BST on 22 July 2021. Trading of the new AstraZeneca shares on Nasdaq Stockholm is expected to commence on 22 July 2021. Trading of the new AstraZeneca ADSs on the Nasdaq Stock Market will commence at 09:30 EDT on 22 July 2021. The Alexion shares will be delisted from the Nasdaq Stock Market and Alexion will terminate its registration under the U.S. Securities Exchange Act of 1934 as soon as practicable following completion of the acquisition.
Indeed, as @random53 pointed out, AstraZeneca acquired ALXN on Monday, hence why no quotes are being displayed for it.
We’re still awaiting further information from our intermediary - IB on how they plan to handle the event.
We’ll make sure to keep you posted 
Thank you both this is most helpful
