Yes, it is post the upgrade for me. It was absolutely fine when I had the visa platinum earlier but the minute I've upgraded it, I'm unable to access the portal.Whoever has been facing this issue with HSBC travel portal not visible- is it when you've upgraded from a previous card to travel one ? I have hit this issue on an upgrade and have seen multiple posts highlighting the same.
I've also read on other threads that after the ticket is raised, usually it starts working in 5-6 business days.
