Hi Michael,
As discussed in our Live Chat earlier, I have escalated this to our technical team who are investigating the issue as a matter of urgency. I will keep you posted of any progress and update you on Monday, when they have had a more in-depth look into what could be causing the problem. Sincere apologies for the inconvenience caused by this recurring issue, we are aiming to get it resolved for you as soon as possible.
If you need anything else in the meantime, please do get in touch.
All the best,
Natasha
