HI @kikass, this is an issue we are trying to fix right now. There is a thread in feedback dedicated to this https://hotcopper.com.au/threads/old-site-return-to-old-h-c-link-not-working.4468063/
If you could post there anything like when it started happening, what browser you are using, whether you were using a private browsing window or (incognito mode or something along those lines) or if cleaned out your cookies recently, would be a help in try to sort this issue out.
