Hi , I am having an issue trying to login to purchase an upgrade to 2023.2

I can login fine on the discussions forum but every time I try to login to the Twinmotion site it fails with a "error.invalidClient.title" error "Not Found" . Same thing everytime?

This is on my PC , MacBook Pro , iPad & iPhone so not device specific

Same for me as well as others i know. I assume there is a large issues on their end.
